Re: what is a good bullet for reloading 7.62x54R ???
I load .308, .310, and some .311 dia bullets depending what type of bullet I want to use. If yours will shoot .308's then your options are pretty much unlimited.
For plinking I pull the steel core bullets from the surplus spam-can ammo and load them with Hornady .310 123gr soft points cuz they are cheap and my local ranges will check your bullets with a magnet. These "mexi-match" loads shoot 1 MOA out of my Mosin.
