bolt guns will always out perform gassers of same quality. my advice is buy a rem 700, savage 10 or tikka t3 with a heavy barrel. they all will shoot 1 moa or less with good match ammo. better with handloads. more importantly invest in quality glass. the best rifle in the world wont do much if you cant see the target.
to better answer your question, what distance will you be shooting? is weight a concern? do you handload?
The right to bear arms is WAY less ludicrous than the right to arm bears!
