Got my .308 Howa back from the gunsmiths recently after screwcutting and picked up some Prvi 150gr SP at the same time. I had not had a chance to get to the range before i had a booked stalk on Sunday. First shot at 30 yards to check it was on paper was a inch left, moved to 100 and 7 shots spread over about 8 inches, adjusting the scope bore no relation to where the next round went. First time with the Prvi SPs but the rifle usually shoots Prvi FMJs at around MOA. The rifle shot badly with Winchester Super X before the chop but not to this extreme. Crown looks fine, he did another of my rifles at the same time which is spot on. Everything tight. You had any rounds shoot this badly before?? Used the estate rifle and got a nice buck but i am a bit worried about my rifle now.
