I had a failure to extract coupled with the round behind it jamming at an angle in the chamber.
I invented new swear words that day along with more ancient curses, not uttered nor heard by human ears since the days of the Aztecs...
Effing nightmare, indeed... Never used steel case again, except where it was meant to be used...in Ivan’s guns.
The AK round has a nice, steep taper to it, which aids in extraction. Not so much for the AR rounds. I think this is why steel works so well in the Rooskie cartridges, even with the lacquer.
