I have an early accumark 30-378, I took it to Zimbabwe last September. I used 180 grain barnes ttsx factory loads. Shot 6 plains game with it. All one shot kills. Impala to zebras to Eiland. One word- awesome!
Awesome. I so want one. My buddy going to build me a custom 30/378
I shot my guides 30-378 when I was hunting the Little Greys River area for mulies. It was very easy to ring steel at 500 yards, and with the muzzle brake the recoil was on the same level as a 270 Win. What a cartridge!
So glad to have stumbled upon this video. I may have 200-400 shots left more than I had counted on. I bought one of these a couple of years ago and my dealer threw a box of cartridges into the deal. In getting the gun on paper it grouped as well as a good varmint rifle could. I went home and loaded up some test rounds, and then went back to the range. My final sight-in group was less than .2" (3 shots) at 100 yards-muzzle velocity averaging 3451fps with 180 GMX. Call me a liar if you like, but the gun room is minus inventory so I could buy a scope worthy enough to sit on the "King of Rifles."
Oh…and how about chambering a few rifles in the 375 Weatherby again. Superb cartridge that would cost nothing to add to the line. At the very least as a Custom Shop offering.
I just purchased a 30-378 Accumark last week. Received the brass I purchased from you folks today, along with reloading dies and other essentials from MidwayUSA. The only thing I am lacking is an optic. Love the Accumark. I currently have the 257 WBY, 7mm WBY and the 30-378 i the Accumark. I do own a Remington Model 700 Classic chambered in 300 WBY. Given the oportunity, and permission from the wife, I would want to get the 300 WBY in an Accumark.
I'd like to see an episode on the dangerous game cartridges, I have a 460 weatherby being built for my cape buffalo hunt
Sweet! Is it a weatherby build or a different gunmaker or some kind of custom rig? I’ve long been fascinated by that monster.
Only Weatherby I have at present is the .257 wby, it’s a hoot but I hope to add a few of the thumpers to the lineup in the future.
Most powerful centerfire in my current battery of rifles is a .358 Norma Magnum that has come to be very dear to me. Love that thing.
The .340 and original .378 weatherby are really impressive to me. That .340 is so underrated for what it is.
@roadkillanonymous4807 it's a custom build from a cz 550 action, I currently have a 30-378 weatherby as my go to rifle and will always grab it when it's crunch time
@@adamt5410 very nice, hear lots of good things about that action.
My .358 Norma is a unique old rifle, a BRNO ZG47 bolt gun, mauser 98 type action and argued by some to be the best iteration of that action design ever made. Inspires all kinds of confidence in its dependability. Was rebarreled to .358 at some point, action itself is kinda neat to me as it says “Made in Czechoslovakia 1956” stamped on it. An efficient cartridge too in conjunction with the long barrel (27.5”) it wears. No trouble getting 280 swift a frames up to 2800 fps for 4800 foot pounds. Doesn’t even kick too much. Not at all 460 weatherby territory though, hope to shoot one of those before my time on earth is up 😁
Ouch!! Lol!! Got to shoot one...im only 5'7 and 180 or so and it was...unpleasant to say the least, BUT knowing what I hit is going down more likely than not males it worth it...see Capsticks account of elephant culling with his Italian client...poor guy put 20-25rounds through in a couple minutes...
This type of programming forum involving general discussions about the various projects and products produced by a company like Weatherby, by some of the main players in those developments...is an excellent idea! Especially, if you all have the time to possibly look at, or even reply to questions or comments by your viewers and consumers.
I have spent a fair amount of time doing research with your various rifles and calibers over the years, starting naturally with a barreled action in .460 Weatherby that was stocked in a very nice piece of Bastogne walnut. It was my first or second rifle cartridge that I reloaded for back in 1973.
Since then I have had every factory loaded caliber produced by Weatherby except the .224, .240, .270 and 7mm Weatherby magnums and the RPM's. The Rocket was not available, but definitely was interesting (as are the RPM'S)! It's hard to imagine just how important the contributions that Weatherby has made over the years to both the sporting and military side of things, but the landscape was changed thanks to your company!
Your company provided the benchmark for a lot of testing that I have done with your cartridges and wildcats based on those and even some that I took several steps beyond, that were not suitable for production rifles/actions. On a number of occasions I would find a good deal on a Mark V rifle and then spend four or five times as much in load development! As one of the very first members of the .50 caliber shooters association, I have done a lot of experimentation with the .50 Bmg and it's alternatives and have written a number of articles for their magazine VHP. Some of the alternatives included .510 diameter calibers based on the equivalent of the Chey-tac case and another based on the .416 Rigby basic case necked to .510". It was on the latter cartridges load development program that I strayed over to the .460 case necked up to .510 (which happened to have a case capacity that was very close to the .50/416!
The limited tests that I did with both showed significant promise with a 32" barreled railgun that I had built for that purpose.
Testing was done with ~ two dozen powders.
Muzzle energies easily exceeded 9,000 - 10,000 ft. lbs and peaked in the low to mid 11,000's with optimum burn rate propellents. Two projectiles approached 12,000 ft. lbs., with one of those (which was a not readily available projectile variant)... exceeding 12,000 within acceptible pressures! This was done with a load of 140 grains of the optimum propellent for those 750 grain projectiles. Briefly, the same Chey-tac equivalent cases were also used to test a .30 caliber improved variant that held ~ 50 grains more than the .30/378 and was found to be overpressure for any bullet weights over 110 grains... with any available propellent! It would handle up to 190 grain projectiles at above case failure levels and below gun damage levels. Later tests with .30 and .50 caliber propellent guns with chamber volumes of ~ 450 - 500 grains and 1,100 - 1,200 grains and l/d = 1 monolithic projectiles of 50 - 55 grains and ~ 225 grains respectively... would exceed the low to mid 6,000 ft./sec. range before hyper-velocity gouging onset would occur (almost every time)! The top velocity achieved (with the .50 caliber 225 gr.) was 6,980 > 7,100 fps... corrected to muzzle with inbore and (non-catastrophic) gun failure!
The last part of this was in answer to the hyper-velocity portion of your program.
By the way... the hyper-velocity gouging is a hard problem to get around in normal environments and with open and probably closed source venues. Sorry about the length of this... lastly, would a possible .40/.416 rpm straight case (or 9.3 RPM) be of any interest? Thanks for all you have done!
I worked a couple years guiding mountain goat. The only round I ever heard the outfitter talk about that really impressed him was a guy who used a 30-378.
I also love the Hammer bullets! I've loaded up a 92 gr Hammer Hunter in my 257 Weatherby and it's going 3866 FPS and shoots .3 inch groups.
Hey there ! Really like your videos. You should see what you could do with 30-378. I bet you the 30-378 would scream with some 110gr or 130gr Barnes TSX or TTSX. I bet you could break 4000fps with a 110gr bullet... A bullet that's actually viable on big game (deer - antelope)...
*I'd rather have more weight with elk, moose & bears. A 180gr mono or bonded bullet... Sounds like the perfect vessel for a 200gr Accubond 😉
@@ashmerch2558 Not sure I'll ever get a 30-378 when I have a 300 WBY.
Like your videos.
@@giljohnson432 Thanks Gil!
@@ashmerch2558 Look up old Roy’s work with the US Army with his 30-378. Check out the mind boggling velocities he achieved.
I just purchased my first Weatherby Mark V rifle in 7mm Wby Magnum. It had been stored in the previous owner's closet for over 40 years! He stated that he had never shot it! What a NICE FIND(closet queen) and in just the caliber I've been looking for...7mm Wby Mag! Gotta decide on what optics to mount on it! This became a birthday present to myself in March 2023! Lol!
Hope you are enjoying it.
So, your rifle came out of the closet? Just kidding pard! In all seriousness, you found a hell of a rifle! Congratulations!
Think South Texas. If you try to harvest your does and management bucks from a stand or tripod with any caliber of rifle or bow, they adapt and move away quickly only to return long after the season is over especially during a wet year. The 30-378 is the perfect load for harvesting deer away from your blinds/stands that typically require a longer shot. That way hunters do not skip on harvesting does & management bucks while they are in the stand and before the rut.
I've been waiting for a video like this for years
These podcast are great.
I found a used 30-378 made around 2004-2007. Still has some life in it. Finally got to shoot it, not a kicker to shoot but it did rattle the windows on the range shack.
My 2 fave rifles are a .257Weatherby and a .30-378...i cant think of any mammal i would hunt i couldnt take with those 2. 30-378 is my all time fave round!! Have been trying to work at Weatherby in Sheridan for about a year, just as a nite...hint hint...lol
You guys make some dang fine products, it’s -20 up here in Alaska and as soon as it warms up I’m hitting the range getting ready for this fall!
The all-time greatest .30 EVER!! Maybe best cartridge period!!! Wish it wasn't $10+ a round, but dang it's awesome!!!
It’s less than half of that
@@danielboggan2479 lmao!!! Not for factory rounds...more like $12+...luckily I reload, but the powder charge is huge and brass is soooo expensive...for top performance I can roll my own for about $6.50
The best PG cartridge if you can handle the recoil.
The use of molybdenum when shooting high velocity bullets back in the day- the 22-250 was my initial fast bullet 50gr at 3650 FPS. I meet a Gentleman at the range that had worked up loads for artillery rounds during the Korea war: he told me it was to save the bore of the tanks and artillery guns. When I started on the 340 Weatherby with 250gr bullets I was able to get excellent accuracy at 3200 FPS- this was my Elk rifle- the shot that really sold me was 585 yards and another hunter came over to me who had seen the whole thing: he couldn’t believe how that Elk literally died were it was hit.
Please make a vanguard in 30-378 a budget monster would be right up my alley
I have a 30-378 Mark v custom for sale.
I have an Accumark and a Mark V Deluxe. Both are chambered for the 300 Weatherby. I use Hodgdon load data for H4895, duplicating the performance of the 308 Winchester. In an 8.2-pound rifle, the recoil is very mild, and the accuracy is excellent. These loads are perfectly adequate for close-range deer and black bear hunting but will not burn barrels when plinking at the range. For reduced loads, it’s a good idea to follow Hodgdon’s reduced load data for H4895 but don’t go too low, or the necks will not seal properly, and carbon will blow back and impregnate your brass, causing it to look like crap - forever!
Additionally, H4895 does not produce that burned gunpowder smell that millions of people have grown to love; instead, it smells like burned popcorn. But the performance is incredible. As for the 30-378…it’s really a bit much.
I would like to see a 7mm x 300 or 378 Weatherby case. A 170 or 175 Nosler Partition bullet would make an amazing deer and elk round. Never have to worry about windage or elevation.
In 2019 me and my son took the Mark Thompson Long Range class and I gotta say for a 63 year old guy that thought he knew alot about shooting learned a heck of a lot of info from Mark Thompson. We both bought the Weatherby Mark V 30-378 and I have shot my New Mexico Oryx at 700 yards and killed a cow Elk at 300 yards
I do all my own Reloading for this gun and am amazed how accurate and easy the Fixed Reticle Leopold scope is consistently hitting targets. We both Love this Rifle.
Keep up the great podcasts. Adam is doing a great job with his hunting podcasts with his wife.
I'm going to drop by the new Weatherby Firearms factory in April. I used to go into the Firestone Weatherby store with my Dad as a young Kid.
Good conversation wish you could cover the guns themselves and maybe the differences that the stocks make if any ?
What would be your recommendation for a Hammer bullet for the 30-378?
How about necking up a 340 to 358 (for us 35 caliber lovers) or even 366?
Then how about chambering the vanguard in 270WM and 7mmWM? (You sales would increase) a hyper velocity 270 option other than 27 Nosler
Maybe a 338rpm necked up to 358 or 366
I have actually thought about a 358 RPM already lol. I would also be up for a 270 RPM too!
358-378
Already been done. It’s called the 358 Shooting Times Alaskan
Will Weatherby ever do another chassis rifle in .30-378? I really wanted a TRR in .30-378...
As an easterner living in Pennsylvania it’s overkill for me so I’ll likely never have one, but it’s cool.
I wish you could release a 6.5x378
It will be too overbore, and throat erosion will start within 200-300 rounds.
I have Like mark an sam after work a 31.5 inch barrel in a mauser 98 custom 30-378 for elr and wow 250 gr happily at 3225 fps very happy and 175-180 at 3700 very pleased
I never had a good luck in a Accumark with heavy bullets...with 165-180s MOA...with 210-225 not so good--I have a custom that Dave Manson did for me we shoot 225s and 230s out of it--and yeah it's king.
Such a cool cartridge. But those diminishing returns are just too diminishing OUT OF NORMAL BARREL LENGTHS. For conventional hunting rifles, I went with my .300 win mag for practicality reasons BUT feel that it’s awfully hard to meaningfully beat the original .300 weatherby and the .300 RUM as the perfect 30 caliber magnums. Roy had a lot right the first time.
I’d rather a 22-240 with a fast twist and heavy bullets, and a 500 on the 460, aka 500 A Square.
Let's just glean over the recoil and expense. lol
I would love it if you guys would do a 7mm-378Wby. An absolute lazer beam and would be good for anything. Im thinking one in the carbon backcountry model rifle would be the ultimate backcountry deer and elk rifle
They’re gonna have the fastest/ flattest shooting cartridge in every caliber before too long 😂
This has already been done. It’s called a Lazzeroni 7.21 Firebird
He used a 30gr bullet in a plastic sabot
I’m alarmed that people who work for a guns ammo company think bullets moving to fast will pencil an animal.
They don’t. If it’s moving too fast they explode on impact.
You are generally correct. There are a few projectiles that can behave differently though...
@@weatherby fair enough, I’m actually really happy y’all took the time to reply.
And for what it’s worth, I like the company and the podcast. I’ve got a Mark V in 300 weatherby I haven’t shot yet, but the gun is beautiful.
Bullet construction will determine that too.
On my hunting guns I like for my bullets to go 3000 FPS and faster.
Need a .257 rpm and 6.5-300 ammo loaded with hammer bullets.
Saying "this is NOT for you" sounds kind of fud elitist. Wouldnt it be better to say "this isnt the best choice"? Because any gun is for anyone because second amendment purposes.
I wish you offered more all copper ammo for 30-378
7.82 Warbird...
