i bought a tikka lite stainless in 7mm rem. mag. I have shot it on two different occasions, putting about 20 rounds through it at each time. The first time was at 50 yards, the 2nd time was at 100. i was using federal premium 150's. now i know they have a guarantee of 3 shots under 1 inch at 100 yards, and im not all that close to that. I know there is a lot of my error in there, but even so it seems like my groups should be tighter. anyone have any suggestions or do i just really suck? please be honest.
