My savage doesnt like the Noslers I cant get them to tighten up, would a magnum primer help? Im using h335 w/ win brass and cci 400 primers, and i still have a little way to go to the lands should i bump the bullet out to fit the mag?I do everything but turn the neck, this .223 savage is a bad a$$ but want it better..any help? I can shoot 50 vmax @ .5 groups @ 100 but about 1.25 w/ the noslers.
