Jump or jam the Berger 108s , using h4895 , tried the 107 smks at various loads and jump , jam , at best was a crap shoot , very inconsistent. This is my heavy gun for 600 & 1000 yds, shoots 105s ok, but not giving me that warm fuzzy feeling. custom Howa 1500 blue printed action, 29in brux 7.5 twist , straight 1.250
