Like I said, the groups went from 2 3/4" to 11/16". That was last Sun at the range. Going to work up some loads for 140 gr MatchKing HPBT's but I gotta find some first. In Alaska, we don't have the best choice. A new Sportsman's Warehouse just opened in Soldotna, I'll give them a call but don't have high hopes. 6.5mm is not a real popular round here. Usually I have to order from outside. I burned up my last MatchKings trying to make the the dang thing print. Should have stopped after the first 20!
