I am still a novice reloader and wonder if a .001 larger diameter bullet is safe to fire in a rifle. I have 3 Mosins (two M44s and one 91/30). The M44s slugged at .312 and the 91/30 at .311. Is it safe to use .312 jacketed bullets in the 91/30?
Absolutely. I don't even hestitate to go .002 larger in cast. .001 larger is pretty much standard for jacketed. I think you'll like the Hornady's . .they shot alot better in my Mosins than any surplus I bought.
The older Ruger Mini-30s had a .308 dia bore while most factory 7.62x39 ammo was .310-.311. The larger bullets were safe to shoot out of the .308 bore.
