great info.... a true craftsman. You can't get no better than this. Any other source can't hold a candle to Randy. Every video is more and more compelling to enrich the sport more and more ! Than you Randy And God Bless
Randy, I have been hunting and reloading for over 43 years and want to thank you for your informative videos. I also agree with you about not buying into all these new hype cartridges when the older ones are fine
Thank you Randy, we are loosing this valuable knowledge. You should write a book my friend. Thank you Cathy, as always top camera work.Kind regards and God Bless from Australia.
Thank you, Randy. They are all good choices. I am partial to the 30 Nosler, have shot a friend's, and hope to be building one soon. I have another friend with a 30-378 Weatherby and you couldn't buy his, twice the price. It's a freight train!
I've built 2 and reloaded 3 300 magnums. 300 wsm, 300 Rum, and reloaded the 300 win mag. The 300 wsm uses 8 - 10 % less powder. And keeps up the 300 win mag up to 180 gr bullets. I built the 300 Rum for longer ranger shooting. Reloader 19, RL 22, IMR 4350, IMR 4831. work good for me. I've used Winchester and Federal pimers. With 150 - 180 grain bullets for deer or elk. Ive reloaded 18 different calibers over 24 years. The 300 wsm is my favorite 300 magnum. less powder and recoil and the best accuracy over a boarder bullet weight point of impact.
Long live the 300 RUM. I remember when Remington released it with power levels 1,2 and 3. It was 30-06 level, 300 win mag and full house and I thought it was a good idea but nobody does it that way now.
@Scotty Davis. That select a level idea was great, but the buying public is sort of fickle on stuff like that. Back in the old days .270 Winchester ammunition was offered in two levels so woods hunters could have a milder less destructive 150 grain deer load. It was about like a .300 Savage for speed and power. Perfect in concept. That load sold poorly and was dropped. Such is the market with buyers. All or nothing.
I hated the I, II, III power levels. If you want 30-06 power shoot a 30-06. The ammo availability in my area was always the 06 level, or occasionally the 300 win level. It was a joke on Remington's part. I like my 300 RUM but Remington did a poor marketing job with it. I recall their original ad campaign comparing the Win, Weatherby and RUM. In typical BS fashion the compared them with the RUM having a 26" barrel and the other two in a 22" and 24" barrel. Like I said I like/enjoy my RUM , but it is not any faster or better than my Weatherby's.
@@hepfarms9101 actually I watch all of Randy's videos. What is your point? Maybe you don't have a point. My point was extremely clear, I am not a fan of Remington's three tier power level in the 300RUM.
I like to hear what you have to say about all you talk about. You are very knowledgeable about a lot of different things in the shooting world But I was wondering What is the best way? To store your powder? To keep it dry for a long time
I was gifted a Winchester Model 70 Pre-64 300 H&H Mag and what I know is a Nosler AB 180gr Bullet going over 3000 FPS will do anything I need to do in North America as a Black Bear found out this spring.
Sir I have 20 inch Tikka t3x light Cut 4 inches off. I use 168 ttsx and 190 accubond. Rifle is 7 pounds with 20 inch barrel 3 port break aics 3.715 mags. I will replace with carbon proof 20 inch barrel with long throat.
I do too. The H&H is the Goldilocks of the the 300’s. If you look at the 300 Win Mag for example, it’s so inefficient. If you don’t want to use the H&H, at least consider the 300 WSM before just getting a 300 WM.
.300 H&H delivers essentially (95%) the same performance as the .300 WinMag. The longer neck increases the stiffness of the loaded cartridge, so if a round hits the ground, the bullet will still be straight. I have a number of friends with .300 WinMags, but the recoil is almost double that of the H&H. As I prefer to watch my misses as they happen, the .300 WinMag doesn't work for me. The long and tapered cartridge body, combined with the slowly tapering neck dramatically reduces recoil and makes operating the bolt much smoother. I have never had a case that was reluctant to come out. Picking up spent brass at an outdoor range, 1/3rd of the 300 WinMag cases I picked up the case head was torn behind the extractor groove. At the cost of belted magnum brass, I will be happy with my 1888 Gewehr and my Remington US Model of 1917, both rebarreled to .300 H&H.
I've had most of these over the years 30-378, 300RUM, 300 Weatherby, 300win mag, 300WSM. These days it's very costly to get good bullets and impossible to find 338cal and 375cal at present. For this reason I've found 270win 308win and 30-06 to be available and at least components easier to find so that's what I'm using. I realize my 270win isn't an 300 Weatherby but at least I can buy ammo and cases to reload for it pretty easy.
About 35 years ago I purchased a bolt action in .300 Win Mag. It's made by Krico, a now defunct company from (the then) West Germany. It's been a tack driver straight out of the box. On one excellent day, I got a one half inch group at 200 yards. That's quarter minute of accuracy. Not bad for an off the shelf rifle. With a hand load I worked up, I'm getting 3,000 fps with a 180 gr. bullet out of a 24 in. barrel. That's plenty enough velocity (and energy) for me. Recoil is stout but manageable. I understand that greater velocity means more energy but if you've got enough, why chase more? I don't do long range shots at game. My solution to a 700 yard shot is to get 500 yards closer. I do some long range shooting at my local range where it goes out to 1,000 yards but to me, hunting and target shooting are two different things. Having an excellent 30 calibre magnum rifle in my .300 Win Mag, I don't see the need for a Weatherby, a .300 PRC or whatever. If I was just starting out, I'd look around... and likely choose the .300 Win Mag. It's enough gun for elk, moose and bears. It's an excellent cartridge for the mountains. If you have to 'reach out', it can do it. (But try to get closer!)
While the case capacities are similair between the 300winmag and the 300PRC, the PRC has 1000PSI more working pressure under SAAMI and because the bullets are seated further out of the case, heavy bullets don't eat up eating case capacity. We're able to see about 10% improvements in velocities between the 300wm and 300PRC and that's significant.
The 300 Weatherby is a timeless classic! Some shy away from it due to cost. The RUM does not really beat it. The difference of 50 to 75 fps is not a real advantage in the field. Stuffing more powder into a slightly larger case also pushes barrel life to a point where practicality is a question. I have found considerable differences in performance between the Weatherby and Winchester. My chronograph testing has shown over 100 fps advantage with numerous weights when compared to Winchester 300. I’ve recorded 3095 fps with 200 grain round in the Weatherby. Accuracy was superb. All in all the 300 mag, for whatever version you pick are fantastic performers.
We are listening and we will continue to listen to everything you have to say until the day you don't. I can only imagine the library of knowledge you have written down
Very interesting words of wisdom. I enjoyed this. It would have been fun to hear you throw the 300 H&H in there. It's my favorite 300. Most efficient, Less recoil and shoots the same velocity with 180 Accubonds out of 26'' barrels. I have all the 300s except the PRC and the RUM. Love the old 1920's 300 H&H. Great video sir.
Randy, thanks for your opinion. I'm a gunsmith also, and I think the advantages of the 300 PRC are that it does not have a belt like the standard magnums which can help accuracy and it allows heavy for caliber bullets and longer cartridge OAL so there is an advantage over the 300 win mag in that regard. Is it a huge difference? Not really, but why not take all the advantage that you can get with everything else being equal. Also, a lot of my customers don't reload, and the other advantage to the 300 PRC is the cost of ammo vs the larger capacity magnums. Thanks again for these videos.
@@TODinWYAs I said, a lot (actually most) of my customers don’t reload, so they’re looking for the best out of the box performance that they can get. Performance for them is accuracy, power, manageable recoil in a light rifle, and ammo cost and availability. 300 PRC ammo runs about $65 per box for hunting ammo and that’s a 212 gr ELD-X bullet at 2900 fps. I’m not sure availability of the brass (I’m sure it not as common as 300 win mag), but the loaded ammo is readily available. With factory ammo, there’s about a 20% increase in performance and still have decent barrel life (compared to other magnums) and low cost of ammo (compared to the hot mags like the RUM and Nosler).
@@redrock425 There’s not as much left on the table as there used to be. I’ve measured SD’s for factory ammo that were in the single digits, especially Berger factory ammo. Our rifles routinely go under 1/2” with factory ammo and we’ve had some that hit sub 1/4”. Once you get to that level, there are so many other variables to accuracy in hunting situations that it’s almost pointless to try for better. The advantage of reloading these days is there are so many cartridges, that it’s hard to find factory loadings for all your favorite bullets. It will be a cold day before Nosler loads factory ammo for a 300 PRC. So if you want Accubonds or Partitions for your 300 PRC, you’re gonna have to load your own. As for 300 PRC vs 300 win mag, if you’re loading your own, 300 PRC is even more favorable. You have a larger case volume, and a wider selection of bullets since you have a longer COAL. You can pick up where 300 Win Mag stops.
🤠 Very good discussion and I can wait to hear more! That being said, I used to have some Bigger 30's, one of which was the Lazzeroni Warbird! It's case water capacity was 130 grains, while the 30-378 Weatherby is 133 grains of water! However, the pressure rating for the Lazzeroni Warbird was 66,000 psi, while the 30-378 Weatherby was roughly 63,000 psi! That difference in pressure, 3,000 psi, enabled the Lazzeroni to push a 180 grain bullet roughly 150 ft/s faster! However, I had to back off on the velocities 150 ft/s just to get it to shoot! It was rated to push out a 180 grain bullet at 3,600 ft/s and a 200 grain bullet at 3,350 ft/s, but backed it down to 3,200 ft/s for my 200 grain Swift A-Frames! So, it somewhat defeated the purpose of getting it in the first place! If I were to buy another 30 caliber (though my 30-06 has served me well), I would choose old Roy's 300 Weatherby Magnum! I have shot and seen game shot with my uncles and friends, 300 Winchester Magnum, 300 Weatherby Magnum,, 338 Winchester Magnum, my 338 Lapua Magnum, and Uncles 340 Weatherby Magnum! To me, the 300 Weatherby Magnum is enough gun, without overkill! I had 3 butchers in the family and they all hated Magnums, due to excessive meat wastet! After 45 years of hunting, I now understand their position! However, you touched on another Very Important Point - Bullet Construction and Selection! This subject is sadly overlooked by too many people and I'm really glad that you brought it up! Thanks again and Keep up the Good Work! 👍🙋♂️
And I Will Just Stick With the 30-06, Because I Now Doubt That I Will Ever Be Going Oversees to Hunt (The World is Changing For the Worst)! The 308 is a Great Cartridge, Just Not As Good For The Terrain I Hunt Out West, Where Shots Tend to Be Longer Than the 308 is Capable Of! @@ChrisEdling
The 308 is a Fine Cartridge and If You Go On Midway USA, You Can Get Factory Ammunition From 110 grains to 260 grain Bullet Loads! Since 400 Yards is As Far As Most People Should Be Shooting at Game Animals (I Would Limit My Shots to Inside 350 yards if I Owned One), Their Isn't Anything In North America That You Couldn't Kill With a 308 Winchester At Reasonable Hunting Distances! @@ChrisEdling
I have loaded/shot/hunted with the Nosler Accubonds for quite a few years with great results. Unfortunately, I have not been able to purchase any 7mm AB’s in quite some time. Very disappointed with Nosler and made the switch to Hammer Bullets. Great support, easy load development, and readily available. Enjoy listening to you Randy.
Thanks, Randy, your decades of knowledge are a gift to all of us, thanks for your generosity and for sharing with us, you and your wonderful wife are the best. Cathy is your rock.
I’d read and cruised through forums for about 6 months trying to decide what to get as a magnum rifle. I live in the Southern US where I can take every larger game animal with .30-06 or .308win, and have for 30 years or so. Decided I wanted to go out west in the future, so I went initially with a .300win mag in a Savage rifle. Shortly thereafter, a friend decided to sell his new Savage chassis style rifle in .338 lapua mag, so I picked it up as well. I’ve shot the .300 quite a bit and love it, the .338 is ridiculously expensive but shoots well also. Thanks for the experience with the bullet types and manufacturers, I’ll definitely be taking advantage of the info! Thanks sir!
300 prc. Modernized 300 win mag. Saami spec’d to stabalize the longer higher B.C. bullets that manufactures have come out with. For getting a custom rifle, as Randy does, pick you poison. In the box store rifles, from the ground up the 300 prc is designed for greater consistency out of the box. But, we all know that the out of the box qualities doesn’t make a better shooter, it’s time behind your rifle building confidence to take into the field.
My Ruger go wild 300 win mag with factory federal gold match 215 grain bergers runs the hole ragged at 100 yards. If our economy ever implodes which it will one day. You are going to be able to find components I.e loaded ammo and cases for the good old reliable 300 win mag more so than any newfangled 300 PRC etc.
Thanks Cathy for your videos with your husband. Right now the prices of 300WM is still the best and casing with 338 Norma is going down with it becoming a new military cartridge, looking on ammoseek
I have a . 338 RUM and the thing just Loves Retumbo with a 250 grain bullet. I also had a couple really nice pet loads with NABLR, but good luck finding them. I even emailed Nosler and they very politely and professionally told me sorry for your luck. What a shame.
Figured out impact of freebore in the 1980’s while working for Bull Wiseman in the 1980’s. I first did this with a 264 Win Mag. Great video. However, if you use some of the newer Powders in a 300 Weatherby Magnum you can hit 3,300 with a 180 Nosler Accubond within pressure designs. Also, grove depth and width impact velocities as well. Rifle barrel has to be able to relieve pressure.
Sir my grandpa built himself a 1 in 8 twist 264. Since the release date 6.5 150 accubond I want to hunt with his 264. It's probably 14 pounds, it mean alot to take an animal something my grandpa built
Hey buddy I’ve never meet you before or had the pleasure of talking to you in person but I do enjoy your videos and knowledge about guns and ammo keep it up! Best regards Weston Baird
For me, not being a handloader or one to buy custom rifles, if I’m buying a new full magnum 30, it has to be the PRC for the heavier bullet capabilities from the factory. However, in the end I would probably go a hair lighter than all of these and run the wsm with a copper alloy 165 grain and forget about running heavies.
Couple years ago I wanted to add a 30 cal magnum to my collection. Was going between the 300WM and PRC. I chose the PRC mainly due to the fact the design is just how the industry is shifting towards. Figured might as well get this. But had I already owned a 300 WM then I wouldn’t even consider a PRC. Not enough difference between them to buy a 2nd gun.
Mine 300 blk 200 yrds, 30'06 800 yrds and 300 prc 1500 yrds. Mix and match bullets between all depending on use ie defense, hunting or punching paper. Everybody is different, every need is different. There are no right or wrong choices. Just choices which is the best part.
The only advantage to the PRCs is an off the shelf rifle capable if shooting heavy for calibre bullets. If you go custom the older cartridges are as good or sometimes better.
Ive found a load that I have never veered from that shoots half inch groups all day long with my 300 RUM. 180 grain Swift A Frame with 100.5 grains of Retumbo Powder. I seat .023 off of jamb point and bump the shoulders .002”. Never felt the need to increase weight or use a Long Range bullet with high BC.
One can not go too far astray using the 30 magnums for game. I purchased my 300 Weatherby almost by chance, and found it to be a solid performer. Just last month a friend and I re-chambered a 30-06 barrel to 300 Winchester Magnum to replace a bad 7 Remington magnum barrel on a Vanguard. We are both experienced elk hunters, using 7mm rounds, and also many larger rounds. But, in the end it is hard to beat a 300.
300 Rum. I built one for king of one mile 33” barrel and it pushes the 245 Berger bullets at 3140 FPS my Chamber is 4.150” and I seat at 4.125” and it’s a hammer only factory case that beats it is the 30-378
Randy my first hunting rifle was and is Tikka t3x lite in 300 winmag. Since I have 1 in 11 twist I use 168 ttsx. And 190 accubonds. My barrel is now 20 inches and i put asr 3 port break. Im 6'5 so that extra 4 inches wasn't fun
Been using the 300WM for 30 yrs on elk, nilgai etc. Great results with nosler partitions. Have switched over to bonded bullets..accubonds and terminal acsents with much better accuracy.
Great video Randy. In my testing, I have found nearly identical results to yours. I tested the 210 Long Range Accubond in a 300 Ultra, 300 Wby and 300 Win. All with 26" barrels and similar throats. It didn't matter how many different powders, primers, etc I tested with each of these cartridges. With a 210 LRAB, and a 26" barrel, ALL 3 cartridges pressured out at 4300 ftlbs of energy/3040fps at the muzzle. There was ZERO advantage for the 300WBY and 300 Ultra, over the 300 Win in 26" barrels. I am convinced the barrel needs to be longer to see ANY appreciable difference between those 3 cases. My buddy is a gunsmith and he found the exact same thing to be true in his own testing but with 180gr bullets. Another buddy just built a 300PRC, we will be testing that shortly. I assume we will find the same thing, 4300 ftlbs. Thank you for spreading the TRUTH! The case size doesn't matter unless the barrel length is there to use it.
@@Dave-cf2ng that's moving! I call N570 "Magic in a can". If you want to get something really rolling, that's the powder to do it. The problems are availability and I hoard my N570 as if it was discontinued. I have 23lbs of it and only use in for special rifle projects where I'm really trying to push the limits. And you may have a "fast" barrel Dave. In my internet travels, I have found my 4300 ftlbs in a 26" statement to be really accurate for those 3 cartridges. Once in a while, you can wring a bit more out. As Randy said, across the hundreds of rifles he has chambered in these cartridges, it's always 4200 ftlbs or so(based on velocities and weights he stated in this video) and I know he usually holds his barrels to the standard 26 inches for magnums for his clients. Unless the client asks for longer. He personally usually uses 27 to 29 inches for magnums.
You mentioned measuring the case head expansion to determine case preassure. I would like to hear more of your thoughts on this. I have read conflicting advice in reloading manuals and gun magazines on this subject. The conflicting information is some say you must use new brass while others say you must use once fired brass. On paper their reasoning for each method seem valid. What do you do and why?
Great video Randy. Good common sense advice on cartridge, bullet, powder and primer interaction. I'm assuming the Win and PRC numbers were in 26" barrels. Personally I have found success with all my 300s (Win, RUM and Weatherby). Recently I've become enamored with the 2nd oldest 300. Not the H&H, but the 300 Savage. I know it's small, old, slow and weak compared to the Magnums, but I really dig the old 99s. Next time I'm in your neck of the woods, I'm going to look you up. All the best to you and your bride for a healthy, happy, prosperous, blessed 2023. Cheers, Jeff.
Sure the .300 win mag and PRC are close at those low weights.. but that is taking the PRC away from what it was designed for. It was designed to fire heavy for caliber bullets. Hornady has a great story on how and why it came to be from custom built .300win mags that were made to accept rounds much longer than SAMMI specs and use short twist rates. Many people only ever look at the 500yrd data and say there is no reason for the PRC to exist... however, if you look at the 1,500yrd data, it is a completely different story. For me personally, I do 90% of my hunting with .308win. I use .300PRC for sport shooting (1,000yrd). If I need something for some longer range hunting (elk/moose/mule), then I have my .338 Lapua which will get the job done on anything in North America.
Thank you again randy for taking time out of your days to to share your expert thoughts and knowledge. I Would love to hear Randy's thought about the 300 norma mag maybe one day on the future
The 180 Accubond is an awesome Elk/large deer projectile. Works wery well in my 300WM, and equally in my 300RUM, which really tests a bullets ability to hold together.
if your hand loading just rebarrel, the problem is factory offerings. When some guy grabs a heavy box of 270win and doesn't have a proper twist, he'll complain its garbage ammo.
@@WantingWilderness Yes. Entry is diameter exit is tennis ball size at 175 yrds. I bought the 270 rounds (.277) 117 gr and 124 gr. I would stay with 117. Start at 57.5 gr 4831sc. 3.25 and start opening up by .05 till pressure heats up.
RL powders are temperature stable. I've heard reports from several sources, not confirmed, that RL has been discontinued. :( I've had no chance to find RL 23. Thanks for watching.
I beg everyone to turn off the comments and just listen to Mr. Selby. The information he’s giving away for free, is priceless. After the video go back and leave a comment. You can absorb his information and read the comments at the same time.
The 300 H&H is still king. It ruled 1000 yrd prone match shooting from 1925 through the early 60's. Some of the best targets shot back then compare quite well with what is shot today. Not only that a M70 can get 4 0f them in the magazine, one more that the 300 Win Mag. It is the most efficient of the lot to if you compare bullet velocity vrs. grains of powder. To top it all off you can feed those empty 300 H&H brass through the action like butter. You don't really notice the bolt working stiffly as you chamber a round. Try that with any other 300 Magnum...
Curious if anyone has experience with 7x65R loads. Looking for data, 175gr for 1:8.5 twist Sauer & Sohn German drilling. Already purchased Hornady 175gr Eldx bullets. Wasn't aware that they tend too come apart too violently. Iron sight appears to be on at 100yds with 175gr bullets.
If you want to buy an off the shelf rifle. Not pay to have a deeper cut throat on a cartridge to allow longer COAL And shoot 200+ grain projectiles. 300prc is the cartridge. 300wm/wby/rum with 200gr bullets start eating case capacity. Once you get to 220gr-230gr the PRC is the obvious winner If you want 190gr or less projectiles, those other cartridges become more advantageous.
I feel like with magnums, the Win Mag/PRC/RUM replicate the dynamic of the 308, - 06 and Win Mag. It's a couple hundred fps difference, a little untapped potential in all of them, and have strengths in different niche sports.
One needs to burn 20-25 gr more powder to equal the .300 Wby. velocity. So, if you like the 30-378 Win. Mag and don't mind the extra cost, overall, of those extra grains in each load to equal the .300 Wby, then go for it. I prefer the .300 Wby, for performance and lower charge for the velocity over same charge in 30-378. Thanks for watching.
I have the 300 Win Mag and 300 Weatherby Mag. RL 26 has proven most accurate and adds 100 FPS. Avg is 3,295 with a 180 Accubond out of 300 Wby Mag with a 24” barrel. Brass is Norma/Weatherby, Primer is Federal 215 M. Barrel is Wiseman 416R Stainless. In door test tunnel. Shooter eliminated. 1/10 MOA. The 300 Win Mag is 3,125 FPS and is sub 1/2 MOA
Great discussion!! I HAVE BEEN USING THE 300WIN mag for 30 years with no issues whatsoever.

Thanks Randy and Kathy for sharing your valuable information with us. God bless both of you as he has us with y'all!
Randy, I have been hunting and reloading for over 43 years and want to thank you for your informative videos. I also agree with you about not buying into all these new hype cartridges when the older ones are fine
Agreed
Thank you Randy, we are loosing this valuable knowledge. You should write a book my friend. Thank you Cathy, as always top camera work.Kind regards and God Bless from Australia.
THANK You Randy for all your skills and knowledge and sharing!!
I am a 300 win mag shooter for
40 years.
Thank you, Randy. They are all good choices. I am partial to the 30 Nosler, have shot a friend's, and hope to be building one soon. I have another friend with a 30-378 Weatherby and you couldn't buy his, twice the price. It's a freight train!
I've built 2 and reloaded 3 300 magnums. 300 wsm, 300 Rum, and reloaded the 300 win mag. The 300 wsm uses 8 - 10 % less powder. And keeps up the 300 win mag up to 180 gr bullets. I built the 300 Rum for longer ranger shooting. Reloader 19, RL 22, IMR 4350, IMR 4831. work good for me. I've used Winchester and Federal pimers. With 150 - 180 grain bullets for deer or elk. Ive reloaded 18 different calibers over 24 years. The 300 wsm is my favorite 300 magnum. less powder and recoil and the best accuracy over a boarder bullet weight point of impact.
Randy, again thank you for your knowledge. As you know, for me at least the .300 Weatherby Magnum will always get it done!

I was gifted a Winchester Model 70 Pre-64 300 H&H Mag and what I know is a Nosler AB 180gr Bullet going over 3000 FPS will do anything I need to do in North America as a Black Bear found out this spring.
Sir I have 20 inch Tikka t3x light Cut 4 inches off. I use 168 ttsx and 190 accubond. Rifle is 7 pounds with 20 inch barrel 3 port break aics 3.715 mags. I will replace with carbon proof 20 inch barrel with long throat.
I like the original 300 magnum, the 300 H&H.
I do too. The H&H is the Goldilocks of the the 300’s. If you look at the 300 Win Mag for example, it’s so inefficient. If you don’t want to use the H&H, at least consider the 300 WSM before just getting a 300 WM.
.300 H&H delivers essentially (95%) the same performance as the .300 WinMag. The longer neck increases the stiffness of the loaded cartridge, so if a round hits the ground, the bullet will still be straight. I have a number of friends with .300 WinMags, but the recoil is almost double that of the H&H. As I prefer to watch my misses as they happen, the .300 WinMag doesn't work for me. The long and tapered cartridge body, combined with the slowly tapering neck dramatically reduces recoil and makes operating the bolt much smoother. I have never had a case that was reluctant to come out. Picking up spent brass at an outdoor range, 1/3rd of the 300 WinMag cases I picked up the case head was torn behind the extractor groove. At the cost of belted magnum brass, I will be happy with my 1888 Gewehr and my Remington US Model of 1917, both rebarreled to .300 H&H.
Amen brother
@@pauldeahl3980what makes it inefficient?
In a pre-64 model 70
I've had most of these over the years 30-378, 300RUM, 300 Weatherby, 300win mag, 300WSM. These days it's very costly to get good bullets and impossible to find 338cal and 375cal at present. For this reason I've found 270win 308win and 30-06 to be available and at least components easier to find so that's what I'm using. I realize my 270win isn't an 300 Weatherby but at least I can buy ammo and cases to reload for it pretty easy.
Been a 300 Weatherby guys for years have 7 Weatherby too both fine rifles , there are 2 types of Weatherby owners those that own and those that dont
About 35 years ago I purchased a bolt action in .300 Win Mag. It's made by Krico, a now defunct company from (the then) West Germany. It's been a tack driver straight out of the box. On one excellent day, I got a one half inch group at 200 yards. That's quarter minute of accuracy. Not bad for an off the shelf rifle. With a hand load I worked up, I'm getting 3,000 fps with a 180 gr. bullet out of a 24 in. barrel. That's plenty enough velocity (and energy) for me. Recoil is stout but manageable. I understand that greater velocity means more energy but if you've got enough, why chase more?
I don't do long range shots at game. My solution to a 700 yard shot is to get 500 yards closer. I do some long range shooting at my local range where it goes out to 1,000 yards but to me, hunting and target shooting are two different things.
Having an excellent 30 calibre magnum rifle in my .300 Win Mag, I don't see the need for a Weatherby, a .300 PRC or whatever. If I was just starting out, I'd look around... and likely choose the .300 Win Mag. It's enough gun for elk, moose and bears. It's an excellent cartridge for the mountains. If you have to 'reach out', it can do it. (But try to get closer!)
While the case capacities are similair between the 300winmag and the 300PRC, the PRC has 1000PSI more working pressure under SAAMI and because the bullets are seated further out of the case, heavy bullets don't eat up eating case capacity. We're able to see about 10% improvements in velocities between the 300wm and 300PRC and that's significant.
You prc fan boy trannies are absolutely delusional
10% huh? Show me your reference
@Sldghmmr338 his evidence is a marketing advertisement 😂😂😂
Race out and trade in your 300WM 😂😂😂
@@Sldghmmr338 Published Nosler load data backs up what he wrote, for whatever that is worth.
The 300 Weatherby is a timeless classic! Some shy away from it due to cost. The RUM does not really beat it. The difference of 50 to 75 fps is not a real advantage in the field.
Stuffing more powder into a slightly larger case also pushes barrel life to a point where practicality is a question.
I have found considerable differences in performance between the Weatherby and Winchester. My chronograph testing has shown over 100 fps advantage with numerous weights when compared to Winchester 300. I’ve recorded 3095 fps with 200 grain round in the Weatherby. Accuracy was superb.
All in all the 300 mag, for whatever version you pick are fantastic performers.
That was very well presented! Very good information to have ! The different powders were covered very well !
We are listening and we will continue to listen to everything you have to say until the day you don't. I can only imagine the library of knowledge you have written down
Most of his knowledge is dated.
Very interesting words of wisdom. I enjoyed this. It would have been fun to hear you throw the 300 H&H in there. It's my favorite 300. Most efficient, Less recoil and shoots the same velocity with 180 Accubonds out of 26'' barrels. I have all the 300s except the PRC and the RUM. Love the old 1920's 300 H&H. Great video sir.
It also separates itself from the 06 when shooting 200+ grain bullets
Especially when hsndloaded
300 H&H also known for how well they handle bullets lighter than 150 grains which the others are not.
Living legend!
Randy, thanks for your opinion. I'm a gunsmith also, and I think the advantages of the 300 PRC are that it does not have a belt like the standard magnums which can help accuracy and it allows heavy for caliber bullets and longer cartridge OAL so there is an advantage over the 300 win mag in that regard. Is it a huge difference? Not really, but why not take all the advantage that you can get with everything else being equal. Also, a lot of my customers don't reload, and the other advantage to the 300 PRC is the cost of ammo vs the larger capacity magnums. Thanks again for these videos.
In this day and age, hopefully short-lived, ease of finding brass has to be taken into account. That puts the 300 Win Mag at the top of the list.
@@TODinWYAs I said, a lot (actually most) of my customers don’t reload, so they’re looking for the best out of the box performance that they can get. Performance for them is accuracy, power, manageable recoil in a light rifle, and ammo cost and availability. 300 PRC ammo runs about $65 per box for hunting ammo and that’s a 212 gr ELD-X bullet at 2900 fps. I’m not sure availability of the brass (I’m sure it not as common as 300 win mag), but the loaded ammo is readily available. With factory ammo, there’s about a 20% increase in performance and still have decent barrel life (compared to other magnums) and low cost of ammo (compared to the hot mags like the RUM and Nosler).
Not reloading leaves so much on the table. I was all for 300 PRC but now a properly throated 300 Win mag seems like a great option.
@@redrock425 There’s not as much left on the table as there used to be. I’ve measured SD’s for factory ammo that were in the single digits, especially Berger factory ammo. Our rifles routinely go under 1/2” with factory ammo and we’ve had some that hit sub 1/4”. Once you get to that level, there are so many other variables to accuracy in hunting situations that it’s almost pointless to try for better. The advantage of reloading these days is there are so many cartridges, that it’s hard to find factory loadings for all your favorite bullets. It will be a cold day before Nosler loads factory ammo for a 300 PRC. So if you want Accubonds or Partitions for your 300 PRC, you’re gonna have to load your own. As for 300 PRC vs 300 win mag, if you’re loading your own, 300 PRC is even more favorable. You have a larger case volume, and a wider selection of bullets since you have a longer COAL. You can pick up where 300 Win Mag stops.
Also standard speed difference per shot was less than 8 fps
🤠 Very good discussion and I can wait to hear more! That being said, I used to have some Bigger 30's, one of which was the Lazzeroni Warbird! It's case water capacity was 130 grains, while the 30-378 Weatherby is 133 grains of water! However, the pressure rating for the Lazzeroni Warbird was 66,000 psi, while the 30-378 Weatherby was roughly 63,000 psi! That difference in pressure, 3,000 psi, enabled the Lazzeroni to push a 180 grain bullet roughly 150 ft/s faster! However, I had to back off on the velocities 150 ft/s just to get it to shoot! It was rated to push out a 180 grain bullet at 3,600 ft/s and a 200 grain bullet at 3,350 ft/s, but backed it down to 3,200 ft/s for my 200 grain Swift A-Frames! So, it somewhat defeated the purpose of getting it in the first place! If I were to buy another 30 caliber (though my 30-06 has served me well), I would choose old Roy's 300 Weatherby Magnum! I have shot and seen game shot with my uncles and friends, 300 Winchester Magnum, 300 Weatherby Magnum,, 338 Winchester Magnum, my 338 Lapua Magnum, and Uncles 340 Weatherby Magnum! To me, the 300 Weatherby Magnum is enough gun, without overkill! I had 3 butchers in the family and they all hated Magnums, due to excessive meat wastet! After 45 years of hunting, I now understand their position! However, you touched on another Very Important Point - Bullet Construction and Selection! This subject is sadly overlooked by too many people and I'm really glad that you brought it up! Thanks again and Keep up the Good Work! 👍🙋♂️
I'll just stick with 308
@@ChrisEdling
NOTHING WRONG WITH THAT CHOICE AT ALL!
And I Will Just Stick With the 30-06, Because I Now Doubt That I Will Ever Be Going Oversees to Hunt (The World is Changing For the Worst)! The 308 is a Great Cartridge, Just Not As Good For The Terrain I Hunt Out West, Where Shots Tend to Be Longer Than the 308 is Capable Of! @@ChrisEdling
The 308 is a Fine Cartridge and If You Go On Midway USA, You Can Get Factory Ammunition From 110 grains to 260 grain Bullet Loads!

I have loaded/shot/hunted with the Nosler Accubonds for quite a few years with great results. Unfortunately, I have not been able to purchase any 7mm AB’s in quite some time. Very disappointed with Nosler and made the switch to Hammer Bullets. Great support, easy load development, and readily available. Enjoy listening to you Randy.
Thanks, Randy, your decades of knowledge are a gift to all of us, thanks for your generosity and for sharing with us, you and your wonderful wife are the best. Cathy is your rock.
I bught my first 300 this year, I went with the 300PRC with 1/8 twist. topped it with a VX6 HD 3-18x44
I’d read and cruised through forums for about 6 months trying to decide what to get as a magnum rifle. I live in the Southern US where I can take every larger game animal with .30-06 or .308win, and have for 30 years or so. Decided I wanted to go out west in the future, so I went initially with a .300win mag in a Savage rifle. Shortly thereafter, a friend decided to sell his new Savage chassis style rifle in .338 lapua mag, so I picked it up as well. I’ve shot the .300 quite a bit and love it, the .338 is ridiculously expensive but shoots well also. Thanks for the experience with the bullet types and manufacturers, I’ll definitely be taking advantage of the info! Thanks sir!
300 WSM
An Randu in detail on the 300wsm would be sweet. think I've heard him talk about it but not much
300 prc. Modernized 300 win mag. Saami spec’d to stabalize the longer higher B.C. bullets that manufactures have come out with. For getting a custom rifle, as Randy does, pick you poison. In the box store rifles, from the ground up the 300 prc is designed for greater consistency out of the box. But, we all know that the out of the box qualities doesn’t make a better shooter, it’s time behind your rifle building confidence to take into the field.
By all accounts the 300 Win mag longer throated will match and even exceed the 300 PRC.
My Ruger go wild 300 win mag with factory federal gold match 215 grain bergers runs the hole ragged at 100 yards.
If our economy ever implodes which it will one day. You are going to be able to find components I.e loaded ammo and cases for the good old reliable 300 win mag more so than any newfangled 300 PRC etc.
A true professional my hats off to you thank you
Great, honest video. Thank you
Thank you for sharing your test results.
Thanks Cathy for your videos with your husband. Right now the prices of 300WM is still the best and casing with 338 Norma is going down with it becoming a new military cartridge, looking on ammoseek
I have a . 338 RUM and the thing just Loves Retumbo with a 250 grain bullet. I also had a couple really nice pet loads with NABLR, but good luck finding them. I even emailed Nosler and they very politely and professionally told me sorry for your luck. What a shame.
I wish I knew half of what you have forgotten over the years Randy sir. Great video to y’all be safe and GOD BLESS
Figured out impact of freebore in the 1980’s while working for Bull Wiseman in the 1980’s. I first did this with a 264 Win Mag.
Great video. However, if you use some of the newer Powders in a 300 Weatherby Magnum you can hit 3,300 with a 180 Nosler Accubond within pressure designs.
Also, grove depth and width impact velocities as well. Rifle barrel has to be able to relieve pressure.
Sir my grandpa built himself a 1 in 8 twist 264. Since the release date 6.5 150 accubond I want to hunt with his 264. It's probably 14 pounds, it mean alot to take an animal something my grandpa built
I’m using 140 and 156gr Berger EH’s in my 264mag. They’ve performed great short and long range.
Hey buddy I’ve never meet you before or had the pleasure of talking to you in person but I do enjoy your videos and knowledge about guns and ammo keep it up!
Best regards
Weston Baird
Amazing encyclopedia of gun knowledge, thank you.
Really enjoyed your comparison
For me, not being a handloader or one to buy custom rifles, if I’m buying a new full magnum 30, it has to be the PRC for the heavier bullet capabilities from the factory. However, in the end I would probably go a hair lighter than all of these and run the wsm with a copper alloy 165 grain and forget about running heavies.
Couple years ago I wanted to add a 30 cal magnum to my collection. Was going between the 300WM and PRC. I chose the PRC mainly due to the fact the design is just how the industry is shifting towards. Figured might as well get this. But had I already owned a 300 WM then I wouldn’t even consider a PRC. Not enough difference between them to buy a 2nd gun.
Mine 300 blk 200 yrds, 30'06 800 yrds and 300 prc 1500 yrds. Mix and match bullets between all depending on use ie defense, hunting or punching paper. Everybody is different, every need is different. There are no right or wrong choices. Just choices which is the best part.
The only advantage to the PRCs is an off the shelf rifle capable if shooting heavy for calibre bullets. If you go custom the older cartridges are as good or sometimes better.
Exactly !……
Ive found a load that I have never veered from that shoots half inch groups all day long with my 300 RUM. 180 grain Swift A Frame with 100.5 grains of Retumbo Powder. I seat .023 off of jamb point and bump the shoulders .002”. Never felt the need to increase weight or use a Long Range bullet with high BC.
🤠 I have had really good luck with the Swift A-Frame's in my Big 30's as well! 😯 It is my favorite elk bullet! 🎯
One can not go too far astray using the 30 magnums for game. I purchased my 300 Weatherby almost by chance, and found it to be a solid performer. Just last month a friend and I re-chambered a 30-06 barrel to 300 Winchester Magnum to replace a bad 7 Remington magnum barrel on a Vanguard. We are both experienced elk hunters, using 7mm rounds, and also many larger rounds. But, in the end it is hard to beat a 300.
300 Rum. I built one for king of one mile 33” barrel and it pushes the 245 Berger bullets at 3140 FPS my Chamber is 4.150” and I seat at 4.125” and it’s a hammer only factory case that beats it is the 30-378
Three cheers for WC860! I have used it in the .378 Weatherby.
Great video and info. Looking forward to a possible 7mm prc video.
Randy my first hunting rifle was and is Tikka t3x lite in 300 winmag. Since I have 1 in 11 twist I use 168 ttsx. And 190 accubonds. My barrel is now 20 inches and i put asr 3 port break. Im 6'5 so that extra 4 inches wasn't fun
Win mag. Love it. Rum is sweet but if I need more. I’ll just move up. Lapua AI
I use the 180 AB. At 150 key hole. Still working on the 190.
Irregardless is a word - thank you for educating me on that point.
@@BPzeropoint OK, Jim. Here is how you deal with the double negative problem. Just say "un-irrelgardless." Triple negative is a positive, right?
This guy is an excellent teacher.
Been using the 300WM for 30 yrs on elk, nilgai etc. Great results with nosler partitions. Have switched over to bonded bullets..accubonds and terminal acsents with much better accuracy.
300 wsm would be great one to hear..
Great video Randy. In my testing, I have found nearly identical results to yours.
I tested the 210 Long Range Accubond in a 300 Ultra, 300 Wby and 300 Win. All with 26" barrels and similar throats. It didn't matter how many different powders, primers, etc I tested with each of these cartridges. With a 210 LRAB, and a 26" barrel, ALL 3 cartridges pressured out at 4300 ftlbs of energy/3040fps at the muzzle. There was ZERO advantage for the 300WBY and 300 Ultra, over the 300 Win in 26" barrels. I am convinced the barrel needs to be longer to see ANY appreciable difference between those 3 cases. My buddy is a gunsmith and he found the exact same thing to be true in his own testing but with 180gr bullets.
Another buddy just built a 300PRC, we will be testing that shortly. I assume we will find the same thing, 4300 ftlbs.
Thank you for spreading the TRUTH!
The case size doesn't matter unless the barrel length is there to use it.
I have pushed 185 Berger’s to 3400 fps out of a 26” barreled 300 ultra. N570 is a great powder for the big magnums.
@@Dave-cf2ng that's moving! I call N570 "Magic in a can". If you want to get something really rolling, that's the powder to do it. The problems are availability and I hoard my N570 as if it was discontinued. I have 23lbs of it and only use in for special rifle projects where I'm really trying to push the limits.
And you may have a "fast" barrel Dave. In my internet travels, I have found my 4300 ftlbs in a 26" statement to be really accurate for those 3 cartridges. Once in a while, you can wring a bit more out.
As Randy said, across the hundreds of rifles he has chambered in these cartridges, it's always 4200 ftlbs or so(based on velocities and weights he stated in this video) and I know he usually holds his barrels to the standard 26 inches for magnums for his clients. Unless the client asks for longer. He personally usually uses 27 to 29 inches for magnums.
You mentioned measuring the case head expansion to determine case preassure. I would like to hear more of your thoughts on this.
I have read conflicting advice in reloading manuals and gun magazines on this subject. The conflicting information is some say you must use new brass while others say you must use once fired brass. On paper their reasoning for each method seem valid. What do you do and why?
.30 caliber, America’s sweetheart
This old boy SHOULD remember when someone said 300. There was ONLY 1 "300", THE 300 SAVAGE.
Have you built and tested any wsm rifles, like the 7mmwsm, 300wsm or the 325 wsm?
Yes, I have, plus .270WSM.
Thanks for watching.
Great video Randy. Good common sense advice on cartridge, bullet, powder and primer interaction. I'm assuming the Win and PRC numbers were in 26" barrels. Personally I have found success with all my 300s (Win, RUM and Weatherby). Recently I've become enamored with the 2nd oldest 300. Not the H&H, but the 300 Savage. I know it's small, old, slow and weak compared to the Magnums, but I really dig the old 99s.
Next time I'm in your neck of the woods, I'm going to look you up.
All the best to you and your bride for a healthy, happy, prosperous, blessed 2023.
Cheers, Jeff.
Sure the .300 win mag and PRC are close at those low weights.. but that is taking the PRC away from what it was designed for. It was designed to fire heavy for caliber bullets. Hornady has a great story on how and why it came to be from custom built .300win mags that were made to accept rounds much longer than SAMMI specs and use short twist rates.
Many people only ever look at the 500yrd data and say there is no reason for the PRC to exist... however, if you look at the 1,500yrd data, it is a completely different story.
For me personally, I do 90% of my hunting with .308win. I use .300PRC for sport shooting (1,000yrd). If I need something for some longer range hunting (elk/moose/mule), then I have my .338 Lapua which will get the job done on anything in North America.
Simply Great beyond this ordinary world
Randy is the absolute best there is IMHO.
It would be so interesting to be able to spend time talking to randy
Thank you again randy for taking time out of your days to to share your expert thoughts and knowledge. I Would love to hear Randy's thought about the 300 norma mag maybe one day on the future
Look into the 300 Norma improved very nice case for heavy bullets
The 180 Accubond is an awesome Elk/large deer projectile. Works wery well in my 300WM, and equally in my 300RUM, which really tests a bullets ability to hold together.
I just enjoy the 30 caliber. Got a long range shooter in 300prc and 308, a hunting rifle in 300 win mag and 300prc
Hard to beat a 24 to 26 inch barrel on a 270, 280 or 3006 hand loads. If twist was spread up to 1 in 8.5 new cartridges are not needed.
if your hand loading just rebarrel, the problem is factory offerings. When some guy grabs a heavy box of 270win and doesn't have a proper twist, he'll complain its garbage ammo.

300 Norma Mag??

We build a lot of 30 Noslers with 210g Bergers. Q.M.M.
I beg everyone to turn off the comments and just listen to Mr. Selby. The information he’s giving away for free, is priceless. After the video go back and leave a comment. You can absorb his information and read the comments at the same time.
300 prc wins it for me. Modern case and chamber design made long range shooting from the get go.
Thank you..
Everytime I watch your videos, I never know your name so I write santa next to each idea you give me.
The 300 H&H is still king. It ruled 1000 yrd prone match shooting from 1925 through the early 60's. Some of the best targets shot back then compare quite well with what is shot today. Not only that a M70 can get 4 0f them in the magazine, one more that the 300 Win Mag.
It is the most efficient of the lot to if you compare bullet velocity vrs. grains of powder. To top it all off you can feed those empty 300 H&H brass through the action like butter. You don't really
notice the bolt working stiffly as you chamber a round. Try that with any other 300 Magnum...
The PRC would excel at the 225-245gr VLD, high BC bullets
Thoughts on 180grain in 300 wsm and 300win for elk?
Have they already stopped running guided elk hunts in Wyoming due to wolf predidation? I have heard the wolf predidation is really bad in Montana.
🤠 Yes it is! 😭 If you come this way to hunt, by yourself a wolf tag! 🐺 One wolf, on average, eats 90 elk per year! 😡
That's a crying shame! Sad
No, though it is very slim. Our son quit guiding as the pickings are so slim.
😭🤯😡
I think if I was out hunting and encountered some wolves, I would enjoy what would happen next.😊
I love this mans knowledge and opinian ! I just wish they would teach him to looka at the camerea
I believe I will stick with my idea since I was 20.
If I need a 300 I will just use my 338wm.
Curious if anyone has experience with 7x65R loads. Looking for data, 175gr for 1:8.5 twist Sauer & Sohn German drilling. Already purchased Hornady 175gr Eldx bullets. Wasn't aware that they tend too come apart too violently. Iron sight appears to be on at 100yds with 175gr bullets.
The 300 Norma Magnum seems to have the best BC in the heavy bullet. The military has just selected it for a sniper round.
The 300 Norma cartridge doesnt have “Bc”. The .308 cal projectiles its fires they have a “ Bc” ……
If you want to buy an off the shelf rifle. Not pay to have a deeper cut throat on a cartridge to allow longer COAL And shoot 200+ grain projectiles. 300prc is the cartridge.
300wm/wby/rum with 200gr bullets start eating case capacity. Once you get to 220gr-230gr the PRC is the obvious winner
If you want 190gr or less projectiles, those other cartridges become more advantageous.
I feel like with magnums, the Win Mag/PRC/RUM replicate the dynamic of the 308, - 06 and Win Mag. It's a couple hundred fps difference, a little untapped potential in all of them, and have strengths in different niche sports.
And a little more throat erosion
Randy, what do you think of Ramshot Magnum powder in the three hundred mags?
I've used it in the .300's and it has worked at times, but not my first choice by a long shot [pun intended].
Thanks for watching.
What about the 30-378 Weatherby mag?
One needs to burn 20-25 gr more powder to equal the .300 Wby. velocity. So, if you like the 30-378 Win. Mag and don't mind the extra cost, overall, of those extra grains in each load to equal the .300 Wby, then go for it. I prefer the .300 Wby, for performance and lower charge for the velocity over same charge in 30-378.
Thanks for watching.
AMEN ! PRAISE THE LORD AND AS ALWAYS WITH YOU RANDY ! BINGO BINGO BINGO !
What characteristics make a cartridge efficient? I’ve always read the read 308win is efficient. What makes it more efficient than a 300 win mag?
Case capacity.
