I've read and heard for years about how most Russian Ammo, while pretty cheap, will ruin your gun. Ruin is interpreted a number of ways, from the metal used in the shell damaging the feed ramp and barrel of the pistol to the lacquer or sealant used around the primer gumming up the gun so badly that's it's almost impossible to clean. I had a case of Brown Bear 9mm that I was hesitant to shoot for the above reasons. Finally, this week, went out to the range to see for myself. Took two boxes of 115 gr "mixed metal" rounds and my pretty new STI DVC-C for a reality check. No misfires, good accuracy for Range ammo and cheap. No worry about saving brass for reloading because it's non-reloadable. Took the gun home for disassembly and cleaning, expecting to see a complete mess; metal remains in the barrel, grimy, black residue inside all the working parts and a slide almost ready to jam. Of course, none of the above. No dirtier than when using Winchester White box and barrel no dirtier than usual. If there was any damage, it was mico damage and not visible or obvious from a functional standpoint. In my mind, the end of a myth.
