Phil I get that. It’d be cool to replicate it today and see what you get for the difference. Not that it matters but it’s always interesting to see what difference there was.
It is a hot rod powder. I figure barrels are like tires and man, 570 shoots for me in the Mashburn and RUMs. I just try not to hammer on stuff and keep the firewood sized kernels cleaned out now and again:)
Just for what it’s worth the temp stable part of stuff is a bit overrated in my opinion. Definitely a thing if you’re redlining stuff in the winter cold temps and then shoot in the 90-100’s in the summer but I haven’t had any issue killing deer, elk and other things if I work up my loads in the...
What scope and mounts are you using on your rifle. While it’s possible the gun is doing it, the other shots being all over the map screams something with the mounts or scope.
Just me but I’d use the slowest powder that fills the case if you want speed. Doesn’t matter in regards to barrel length. The fastest fps with a long barrel with be the fastest with a shorter barrel.
I’d think 2900 with a 140 AB in your 19” barrel should be fairly easy. I’m using RL23 in a 20”...
Makes sense to me. I’d use all of the 120’s up. If they’re killing deer the way you want then there isn’t too much reason to change. A faster twisted 257 could be a lot of fun in the right rifle.
Same here Jim. A 7 Rem was my first BG rifle. I used it for woodchucks, deer, bear, crows, moose, coyotes, caribou. If I was a smart guy, I would have had one built like my Mashburn and been a happy camper. The Mashburn is just about everything I need but the 7 REM would have been just as great...
For sure. I’ve converted a 338 Win to 35 Newton which I used 375 Ruger brass to make. Rifle fed like it had eyes with empty brass cases. No need to mess with the rails. You may need a stronger mag spring to push the heavier bulleted rounds but that’s a big maybe as well.
Jim beat me to it. Neck them up to 7mm and then create a false shoulder and enjoy increased case life and no need to burn up bullets and powder just to form cases.
I ran a 130 ABs into water jugs point blank at about 25 yards from my 264 WM at around 3350. Bullet holds up very well and also hunts pretty well.
Like Ernie said, I’d likely opt for 140’s but if I had a pile of 130’s I’d hunt happily.

The 180 BT is way better than it gets credit for in its relative toughness. I’d have 0 concerns with running one into an elk from a 300 mag. Seen it done and it didn’t leave anything more to be desired.
If you can get that 175 ABLR to shoot it is a wicked bullet. I’ve had nothing but excellent results with it in my Mashburn out to 600’ish on elk so far. I’d always thought the ABLR may be too soft but to my liking it has worked wonderful.
I agree with Jim but if I was shooting smallish deer with a 257 Roberts I’d be in on the 100 BT myself. But saying that, 2850 with that 120 PT is more than capable of opening much further than what you’re planning to shoot. Run it through a ballistics ap and see where it his 2000FPS and use...
