TT-33 Tokerev shooting 30 Mauser

Comparing x 25 to x 25 out of my TT-33. Unforunately the 30 mauser () was too old and the primers didn’t have that much pop left in them. I think the surplus is to fast for the gun and hoped I could slow it down a bit. Unforunately I didn’t have good ammo for the test.
