I have never encountered an issue with the Russian stuff. However, I'm getting out of it for my Mini 30, though, and won't run it in my new 911-9 as the bullets are Bi-Metal clad and will eventually create some barrel wear.
Which brings me to the next issue. Bought a few boxes of what was supposed to be Federal 9mm FMJ but turned out to be something called "Hotshot Elite" mfg'd in Slovak Republic. Everything I can find on it says it's safe, reliable, etc but it looks like the bullet may be Brass jacketed. In that Brass is a lot harder than Copper I'm not sure about running it in the new gun. Anybody know anything about this stuff?
