Berger 156 @ 3050' +/- with 20-22" barrel

[260shooter]

Awesome!! I’d go 22”. Extra 50-60fps to ensure your goal and you won’t notice it in the field.

I see most people were shooting H1000 in the info you got. I think a 156 would create an enough pressure that you could use N570 and be right near a full case. In all the cases I've tested, if you can fit a full charge of N570 it produces about 100fps faster velocities than H1000. I don't really like N570 in the bigger cartridges paired with small bores. BUT if velocity is the main goal, it normally shoots great, has low ES and absolutely gives you velocity.

I just bought a 21” 6.5-7PRC. I was just going to shoot 140 hybrids to try and keep the speeds up with H1000 or N565

You should see 3150-3200 with the 140"s.

That would be just dandy with me

I’m getting 3050 with a 26” 6.5 PRC. N565 @ 59.2

Had another load at 3109 but only got 3 reloads before loose primer pockets.

Late to the party, I’m shooting a 22 inch 6.5 SAUM over retumbó and 156s at 3000 fps, hits deer like a bolt of lightning! Enjoy your project!
