A friend of mine[honestly] has a Sako 75 in .308.I have seen him on the target and on the hill and the rifle shoots sub .75 groups with factory ammo.the interesting thing is that the rifle seems to crimp the bullet end of the fired cartridge.The crimping is not always uniform but is very noticeableThere are no powder marks on the case and the primer isn`t damaged.He doesn`t home load and these are all factory rounds.I have asked a few friends who home load to have a look and none of them know what is causing it.So anyone out ther got any thoughts .The rifle is ordinary in every way.Ammo used norma 150gr bt.
