I am currenlty considering an X bolt I have a browning sarfi grade BAR in 338 win mag with the boss and can shoot 3 shot groups at hundered yards you can cover with a dime.
usinging winchester ballistic sliver tips with the boss only moved to the sweet spot love this rifle I am a lefty so semi automatic was my choice because couldn't find a bolt or X bolt at the time. And the Bar I have even though its 338 win mag has less recoil then my 223 my daughter loves the gun if she had her way it would be hers heheh
