6.5 x 55 loads
Thanks for the response. I finally got to the range this weekend and got good results with :
1. 40.5 gr of IMR 4350 156 grain Oryx ( 2.5" 5 shot group- probably me or the stiff crosswind or both )
2. 42.7 gr of IMR 4350 140 gr Sierra Gamekings (sub moa 3 shot group)
Roman you are right, I do live in the southern part of the U.S. and do not know where to buy Norma or Vihtavuori, the IMR 4350 is a slow powder and almost fills the case, but not quite.
