Custom built on a Rem 700 sa 26" 9 twist barrel. Special ground reamer made to my specs for the 140 Berger hvld. I just got this thing put together earlier this week. Formed a few round of brass loaded them back up with imr4451 and 120btips touching the lands at 2.790" and br2 primers. Started at 49 gr worked up to 52. Could go more but can't any any more powder in the case without compressing. The 52 gr load showed 3380fps average on the magneto. Primer is just starting to flatten still has rounded edges and no ejector Marks. And half moa groups to boot.
Shot again today with 50grs and it is right at 3250 for 5 shots
I built 2 7/08 ackleys I think I'm gonna have my customer work up with imr4451 and 120s just to compare
