Now that I've got a small stash of Federal GMM for my M49, I'm thinking of loading some factory-equivalent WCs for practice. This is going to be in mixed brass from a 1-7/8" barrel, fired DA, so I'm not sure it really matters, but I also have a brace of M14s that need to be fed. I'll be using coated, mass-produced cast bullets. Does one tend to be more accurate than the other? My usual supplier (Brazos) only offers the button-nose variety.
