I have a buddy that we reload his 280AI for and use 140 Accubonds and RL22 with WLR primers, but going to try WLRM primers to see if we can get more gas and tighter groups. Next he wants to try the 168 VLD's and see how they do. I have read good things about using magnum primers in the 280AI.
I never noticed a change in accuracy using the Fed 215M about the only thing I gained was lower ES and I was mid 3000fps with 160gr AB.
Well good luck
