Cartridges for the new 85.5 grn. Berger

[gtl1946]

I have just got back my 223AI with a 7.7 twist ABC barrel hoping that they work out for 600yds well. I have some Rem.SA’s that have been blueprinted and waiting for a project. I have one in 308 bolt face and another in 223. I’m leaning towards the 308 bolt face and looking for choices but I don’t have to destroy barrels in my quest to make that bullet/cartridge combination work....distance would be 500-1000yards.Purpose... because!!! Also ,what twist would you suggest .

22 Nosler, 22 Valkrie, 22-250 AI a minimum 1-7 twist. better yet a 6.5 twist. And I would go to 22-250 AI.

I mean this clearly goes hand in hand with the 22x47 Lapua

22 creedmoor with a 8 twist...

It will depend on your altitude, velocity and temperature according to the all-knowing Berger Stability Calculator. Straight up 59 degrees and zero altitude needs a 1:7.25" but I'm using a 1:6.5" with my 22 Creedmoor and it's working well out to about 800 yards right now. I can also handle the 95 grain Sierra in the same barrel.

22 BR with a 6.5 or 7 twist barrel sounds just right to me.

22 Creedmoor 1/8 twist will handle just fine.

22br or 22-250AI.
