Q: I’ve been shooting Russian-made 7.62×39 mm ammunition in my Ruger Mini Thirty. The steel cases are coated in some sort of lacquer for corrosion protection, which I think has been causing rounds to get stuck in the chamber. My brother has had similar issues, and he said the lacquer is causing a residue that is very difficult to remove—even after a thorough cleaning. Anyhow, I believe that this cheap ammunition is a failed product that is being offered and that NRA members should be made aware of the issues.
A: Thank you very much for your question concerning functioning issues of steel-cased ammunition in your Ruger Mini Thirty rifle. This is a sensitive, and sometimes emotional, subject for a number of 7.62×39 mm shooters. Needless to say, proper, efficient, and accurate functioning of firearms, especially autoloaders, requires that the firearm and ammunition “mesh.” In other words, the maker of the firearm and the maker of the ammunition must know and appreciate the dimensional and performance standards of the other party. It would do neither of them any good to design and develop their products in total isolation. That would represent not only bad business practice, but also lack of concern for consumer satisfaction, not to mention consumer safety.
