Ah ok.

So proper maintenance and properly loaded rounds and it's all good.
Good.
I've fired thousands of rounds through my AR and not cleaned it for a couple months or so in a stretch, and even the notoriously dirty rifle didn't start sticking on me, so with something like a PSL, you'd have to neglect it for a LONG time before it jams up on you.


I would probably clean it a lot more.

Since the rounds that I would be trying to use is the Barnaul or Bear ammunition. The paint or sealer they use around the primer to seal, breaks off and coats the bolt head. As seen on my Mosin Nagants.
