Cz457 Accuracy expectations
These are my groupings today at 50y with 3 types of ammo in a 457 American, xrs, timney, huxflow. CCI SV, Norma Tac, Lapua CX. Looking at these groups I’m not entirely pleased, felt that the Lapua should have performed better and now I’m doubting the rifle and considering a Bartlein re-barrel? Is that needed or do I need to not expect a .2 every group with any ammo at all? Have a 455 varmit I can barrel swap as well as this is a spotter contour. If it’s a lemon, barrel recommendations? Thanks.
