Press down on top of the scope with your non trigger hand.. really helps with groups and that muzzle jump after the shot. Gun builder showed me that and it immediately improved my groups with the magnum cartridges.
I've only used Federal 215 primers in my Weatherby cartridge handloads. That's over thirty-plus years and counting. IMR-7828 is still my preferred powder, even though I have achieved good results from a few others.
Pac Nor barrels installed one of their three groove super match barrels in 10T for me, accuracy in their zero freebore chamber with 100s at 3850 and 115's at 3600 has been sub 3/8", without a lot of load development. R#22 with Fed 215s is what I use. IN a friend's 26", 257 Weatherby, he is shooting R#19 with 85 and 87g bullets at 4200 fps with small groups. 87g Speer hot core is a deer bullet with the 80g Barnes TTSX being an incredible deer bullet. I highly recommend Pac Nor three groove barrels with throat to match the bullet you want to shoot.
I bought the Hornady reloading manual and Nosler reloading manual because of watching your channel. Consumer tip, right NOW Grabagun has 7mm RUM loaded ammo for $69.99 a box.
It helps, but handloading components are still paramount to precise accuracy. Usually, maximum OCL recommended in Nosler and a few other loading manuals addresses the issue of achieving sub-MOA accuracy very well, as far as free bore is concerned. It's worked for me and the eight different Weatherby rifles in my collection that I have handloaded cartridges for in the past thirty years.
@@bustabass9025 I shoot Chambers with zero and .030 freebore, with another at .085. Longer 133 and heavier bullets may need a tad more freebore. IN six different 257 Weatherby's, R#22 with a fed 215 is awesome with 100-120g and R#19 with 85-87g bullets.
Haha, love how you got your buddies to shoot the 45-70 loads. With that shaky shooting table I wouldn't expect good results, a bipod with on the ground would be much better and is what I do. If you can't get the 190 ABLR to shoot in your 300 Bee with RL 22 maybe they will work in the 30-06 we see you work with on the channel. Love the looks of that loaded 110 AB in the 257.
The longer 200 gr AccuBond give me fits in my Sako Gray Wolf chambered in 300 win Mag. Dropping back to the 180's made everything better. With the 257 and AccuBond, testing Magpro powder, working up a load, first range trip allowed me to meet and exceed published Nosler RL-22 max fill speeds with 70-71.5 grains of Magpro and no signs of over pressure. I have made a second run that I still need to shoot that are 71 to 73 grain fills. I made enough this time to also test for groups once I figure out where my speed tops out.
Any particular reason you want the ablr to shoot well? My rifle loves the 210 vld bullet. Stacks them in there at around .75" groups. My rifle is also a vanguard so I see no reason that yours wouldn't potentially like it. I have no idea what the oal length is but it was a load by hsm ammunition so I feel sure it's at recommended oal or slightly shorter.
Someone out there has in stock Mossberg Patriot 375 Ruger caliber, cerakoted, synthetic, with metal sights. I think some can be had from just over $400 and I have seen 375 Ruger ammo online for about $70- 90.
The problem might be the technique you use when shooting. I found my accuracy improved greatly by just holding down the forend. The muzzle kick up could be what’s opening up your groups.
I don't know what distance you want to shoot the accubond long range, but to be honest, 1 and a half moa will be plenty accurate for hunting most ranges. Like you, I like sub moa groups for hunting, but it is what it is. I'm glad you're not giving up.
@ReloadingWeatherby We gun nuts are what we are, and it builds a lot of confidence to know exactly what to expect from your equipment. A lot of hunters happily hunt with a gun ammo combination that those like us would never use, but it is what it is. Speaking of overpreasure, I got a good story from over the holidays using a powder I could find no data for, I finally saw what was overpreasure in my 6.5x300. Needless to say, 4100 fps is not what I was shooting for with the 125gr hammer. Being stupid, I thought it was the chronograph, and a sticky bolt and I shot a group without looking at the brass. It was actually an moa group. I would like to think I'm smarter now.
Just a suggestion or 2, put your off hand over the top of the scope on the elevation knob. Take you .300 Weatherby to a competent gunsmith and have the magazine box extended so you can load to maximum performance and get your bullets closer to the lands. JMHO.
Pressing down on the top of the scope, actually will bend the scope, try looking through the scope while aiming at the target and press down, get ready for a shock. I seat those bullets way out in the 257, The throat is .375 long, do not worry about the length as long as it feeds and fits in the magazine. If you can reach up and hold down the forearm while you are shooting, groups will improve dramatically. The Bullet is in the barrel approximately .200 of an inch while the gun is under recoil, with the muzzle flying all over. If you can hold down the forearm, you are going to get a real shock in terms of how the groups tighten up. I shoot in the realm of 68-69g of R#22 with Federal 215 primers sealing the deal. The IMR 4350 is too fast for the 257 Weatherby. Speed on the 257 Weatherby copper fouls the barrel, look in the muzzle with a small flashlight. I use Montana Extreme Copper Killer on a wool mop to get the copper out. Also, I cool the barrel with 50/50 Water and Rubbing Alcohol, saturate the wash rag with the solution, and rub the barrel, you want to see the solution dripping off of the end of the barrel, will cool things down real fast. Best wishes!
Omg if holding down on the scope tube is bending the scope you need to invest in a scope that cost more than 10 dollars,or better check the screws on the mount

That wobbly table is doing you no favors at all, it makes all your data suspect. Is it the rifle or the table? There must be a better solution out there that doesn't cost a fortune and doesn't weigh as much as a Buick.
Your load development technique is all over the place changing primers and seating depths going from old cases to new cases it’s hard to learn anything from load testing if your changing two or three things with every new load so you have no idea what made the group better or worse when you change several things! Your also to dang worried about velocity velocity velocity which is a beginner mistake you will always find better accuracy by giving up a 100 or so fps instead of always trying to push everything right to the ragged edge and over!! Another tip you might find useful instead of using wetherby brass use Norma brass! Norma makes all wetherby brass and it’s half the price!! Norma 50 pieces for 100$ vs wetherby rebranding Norma brass and charging 60$-80$ for 20 pieces!!
Really? ALWAYS find better accuracy 100 fps slower? Ha. That’s bs. Very very often best loads are at or near max velocity. The whole point of Weatherby cartridges is velocity, so yeah of course velocity will be a priority here. Also yesterday I bought Weatherby branded brass 50 pieces for $100 it’s the same price
A lot of assumptions from you. Let's answer your worries. 1. 300 Weatherby brass is the same. 2. My new brass for 257 is the brass I'm going to use going forward. I needed to see if it got the same accuracy. 3. Have you ever reloaded a Weatherby cartridge? They don't shoot as well with lower velocities. Not to mention my 257 load is 2 grains below max and the 300 WBY load was 3 grains under max. 4. My 300 WBY shoots better with the F 215 primers. I switched to CCI 250 because I have more of them and I'm finding out how they work in my rifle. 5. If I could find Norma brass... I would get it. Also Norma no longer makes Weatherby brass. Lastly... Norma brass is still expensive. It isn't 2019 anymore. Box of 50 cost $110, Weatherby brass box of 50 is $120
@@ReloadingWeatherby They don’t shoot as well at lower velocity’s?? If you start at minimum and work to maximum you will find several points in there that the rifle will shoot under moa! Velocity is not where accuracy come from if this was the case then all cartridges would be simple to load for because all you would have to do is load to a predetermined velocity. This is the misconception with weatherby cartridges because they were the fastest at there time so everyone thinks they won’t shoot unless there loaded to max velocity and that’s not the case! Max load is not what you should shoot for it’s a lot better to back off max a lil take it easier on the rifles throat and your brass and set in a node that’s a lot less finicky to changes in conditions and seating depth!! Iv ran them hot and hard more powder more pressure more throat erosion more changing seating depth to keep it in tune pain to keep a rifle in tune if your always changing something with your load every 50 to 75 rounds to keep it in tune! Case fill volume will help you more in finding a good even load more than chasing velocity’s will! Like imr 4350 in the 257 that’s not the case fill your looking for 84% at max charge is low it’s hard to get good ES this way should shoot for 90% min or more you will find way better accuracy and consistent velocity above 90% fill that powder is to fast!! Another thing bonded bullets are just picky they all are a trick iv found is to run an expander mandrel after you size your cases and only run a tho to a tho and an half max neck tension on those bullets and they like more jump than a standard cup and core I always start them at 50 tho out the lands and work away between 50 and 100 or so tho they will shoot!! Can’t always get to 50 tho with the wetherby free bore then I start at max mag length minus 25 tho so the function without issues!!

Iv ran them hot and hard more powder more pressure more throat erosion more changing seating depth to keep it in tune pain to keep a rifle in tune if your always changing something with your load every 50 to 75 rounds to keep it in tune! Case fill volume will help you more in finding a good even load more than chasing velocity’s will! Like imr 4350 in the 257 that’s not the case fill your looking for 84% at max charge is low it’s hard to get good ES this way should shoot for 90% min or more you will find way better accuracy and consistent velocity above 90% fill that powder is to fast!! Another thing bonded bullets are just picky they all are a trick iv found is to run an expander mandrel after you size your cases and only run a tho to a tho and an half max neck tension on those bullets and they like more jump than a standard cup and core I always start them at 50 tho out the lands and work away between 50 and 100 or so tho they will shoot!! Can’t always get to 50 tho with the wetherby free bore then I start at max mag length minus 25 tho so the function without issues!!

Try a new table
Haha yep
