110gr round nose Hornadys. I had a pound of IMR 3031 sitting around and the only projectile in my manual for 7.62x54R with that powder was the 110 gr. I did a box of it a few months ago and had no problem hitting plates at 100yds and there was essentially no recoil.Bingo! Like other weapons the Finns made, this SMG was top of its class. Best accuracy and a drum mag design that was copied and made popular by the Soviets. Expensive to make, however.
Daekken, what size projectiles?
I've never shot my Mosin at an actual target (just plates), so this will be interesting.
