I just run a few brass cased rounds at the end of my session. Works for me.
Apparently the issue is the gunk that builds in the chamber, has a greater affinity for brass, than it does for the coated steel from whence it came. So, if that's the case, running a few brass casings while it's still warm and fresh, and doing so as the last few rounds at the end of a session, is a nice way to clean that out under controlled and non-urgent conditions.
Works good for me at least - I never have a problem with Grendel and steel. But then, I also reload, so running a few 7.62X39 to 6.5 Grendel fireforming shots at the end of the session is a pretty low-cost fun-shooting thing to do. If you don't reload, and are having to do that with $2/shot factory priced ammo; that's probably less attractive.
