I have been out this evening to re zero with some factory ammo. I have had inconsistency problems with my parker hale in 308 and so I thought I could eliminate one variable by using factory loads rather than home loads.
Well the first three shots were near touching. I was quite surprised (75 yards off of a bench bag). I let it cool for twenty minutes or so and fired another two shots and they were slightly left so i adjusted the scope to come nearer the point of aim and fired 3 more shots with minor adjustment in between.
I let it cool again and put a new target up. And the old problem appears again. It shot high and right by several inches. So I followed up with three more shots. Which crept down and left.
Is it me or the gun. But more importantly will the rifle be zeroed to the right point next time I use it.
