Literally? Its bang for the buck! The full sized 91/30 = average rifle firing.
But the M44 or 38 carbine? Huge muzzle blast and fireball! Makes it a more fun rifle to fire

And unless youre standing behind the shooter..ie if off to the side..you will feel the blast hit you and the ground youre standing on like when I took this vid...kinda cool. This old sled dog really steals the show and everyone is lining up wanting to try her out over and over. You dont get this with a 91/30. We had prob 12 different rifles and a shotgun between friends at the camp to share and try out last month.....all I can say is I didnt bring enough 7.62x54r to meet the demand. Everything else was ignored after I introduced my Polish gal.
Heres a grainy pic I extracted from cell ph vid of a friend firing my Polish gal with surplus Chinese ammo.
