G,Day Macca ,
My 280 AI has a match barrel .310 neck, long throated to suit 180 Bergers so all my cases are neck sized too .307" (loaded round) It seems to like Hybrids more than VLD's .
( I DONT RECOMEND ANYONE TO LOAD TOO THESE RATES BEFORE STARTING 10% LOWER AND WORK YOUR LOADS UP IN INCREMENTS OF .3 of a GRAIN AS ALL RIFLES VARY ) I run Federal 210 primers ,Running 50 grains 2209 with 00.10 " jump. I have run 2217 @ 59 grains with good results as well 2217 powder is a bit slower burning, but you can't pick the difference in accuracy , I personally think the rifle is a little smoother to shoot on 2209 if that makes sense burn rate just seems smoother ( can't explain it any better than that )

!
When I ordered that stock I did have a few misgivings wondering if I had made the right decision

, but honestly I may have been lucky Dunno, it is an excellent stock and I don't have any regrets about purchasing it what so ever .
