I have a mod 12 F/TR, which is generally a pretty good shooter - I get 0.5" groups for 5 shots at 100yd on average, and often a bit better than that. I am using 168gn Sierra MatchKing projectiles at 2845fps (measured).

I am basically looking for any suggestions that anyone might have to make the accuracy and consistency any better than it is now, without going to a match-grade barrel. I have already changed the factory cheekpiece for a Karsten one, and I am using a Nightforce NXS scope and mounts.

Has anyone done any modifications to their mod 12 Target rifles? Do they benefit from doing some bedding or action truing work? Anything else anyone would recommend?

I have been toying with the idea of changing it from .308Win to 6.5x47Lapua, so if I go down the match barrel route, that is probably the direction I will go.
