That’s a completely cool rifle ET. I love the 7x57 myself. I have a couple now and I’m expecting the next one to show up next month.
That one you described sounds awfully nice.
I think anything in the 4895 to 4831 should work great in that monster case. I just started using 17 back then probably cause I had a lot of it. 19 and 4831 would and do work great.
I’ve used Magnum, 26 and H1000 with the 129 ABLR and 139 Scenar in my PRC. I like 26, but there are so many great powders in and around it I’d never blink if I didn’t have any.
My favorite deer load is a 140 BBC with RL26 in my old M725 280 Remington. The 140 Sierra SBT is good as well. That load is good for 3100.
In my M7600 I use the 145 LRX with H4831SC. That load is a 2975 and very accurate as well.
280’s a good one. Which rifle did you get?
I’ve used a lot of 17 in my 348 and still do. I’d use Super in a heartbeat if I needed to though. Take a look where it falls in burn rate and drop to the fastest listed powder for charge shown and work up. I know it’s nice to have book data but sometimes a little caution can get it done.
Ha. I doubt it Heath, but it just goes to show, sometimes things are different than what makers say they are.
Have you ever checked the twist on said rifle?
I wouldn’t sweat a 1-12 in a 308. I’d want more, but a 1-12 will stabilize a 208 AMax which you won’t have to worry about in your mag, but it will stabilize it fine.
Don’t be scared of pouring on the powder in BARs. Their lockup and gas systems will take full snort stuff without a hiccup.
My team took one of our M40’s to Quantico in 2006. The data book showed about 10k rounds on the gun. They wanted to get it ready for our upcoming deployment. At the 1000 yard range my buddy proceeded to put 10 rounds through it in about 8-9”. As a gun nut I was was amazed it still shot that...
