Takarev ammo
All right, I admit it, I was trying to bushwack all the guys that think Tok ammo is loaded way hotter than the Mauser ammo. Of course my broomhandle works just fine with 7.63 Mauser ammo because the two rounds are loaded to the same pressure. When the Russkies copied the Mauser round they DID NOT increase the loading. The Mauser was chambered for the 9X25 Export round, which makes the 38 Super look puny (128gr @ 1360), and it had no trouble handling that round. Try rechambering a 9mm Tokarev to 38 Super and see how long it lasts. Put in any spring you want. It would beat itself to death before you went through a box of ammo. The russians never loaded any extra hot sub gun ammo, that is a myth. Before shooting ANY old gun, put new springs in it. Google up Wolff Gunsprings, they have springs for damn near anything that shoots, The set for my Broomhandle was about thirty dollars, including shipping.
