22-250 AI

[malcarjeb]

Has anyone tried the 22-250 AI with the heavy bullets from 80-90grs? If so could you give data with velocitys and barrel twist used. I was looking for a case that you could get enough slow powder in to make the 80-90s work with out going to much overbore. I also was thinking about maybe the 22-6.5x47 lapua.
Thanks for your help

I've had 80g A-Max's up to 3400 from a 1:8 twist 26" Douglas barrel. However, they didn't seem to like that speed. 3100-3200 was the spot for my barrel. BTW, my barrel is a straight taper to .650".

Almost forgot - R22, Win brass and WLRM primers
