I read in some magazine years ago that the Russian steel cases are coated with lacquer to prevent rust.

When fired, the heat melts the lacquer and coats the inside of the chamber. Over time it builds up in the chamber and becomes like glue.

I read the same thing. I tested for it by extracting the bullet from the case, emptied the powder, and discharged the primer. Then took a torch to the empty case. No lacquer ran off. So i figured it was “urban legend”

I was wrong about one thing. The ratio was 1 brass to 9 steel.
