Stuff is 7.62 x 51 Cavim. Has so much asphaltum "sealer"
that it will lock up the HK in 2-3 rounds. Switching to WCC
or R-P commercial ammo and firing 2-3 rounds wil "clear" the
bore of the sealer, then will fire 2-3 of the Cavim again.

Good brass, so just need to remove the gunk and brighten it
up a bit.

Several thousand rounds, so vibrating/tumbling doesn't seem
to be a viable option.

thanks

A bit of solvent on a rag. DON'T soak them! What shape is the powder in
them? Sphere, rod, etc. You might tumble them but that might grind the
powder into...powder if done too long. Tumble a few for a period of time,
pull a bullet and inspect the powder, repeat.

oops, sorry.

Didn't mention, these are fired cases needing to be cleaned
before loading.

thanks

Do you mean "Switching to WCC or R-P commercial ammo and firing 2-3
rounds" clears the bore, or the chamber?

Option one would be a cloth with solvent, and wipe each round down
before loading. Or get a bowl, "dunk, wipe, place in clean pile;
repeat."

Alternatively, load two round "dirty brass" two rounds "clean"...

It's eight fifty eight. Close enough!

In that case, soak 'em. Then wipe each one as you dry them off.
Or rinse and inspect after drying.

HK's (G3, CETME, etc) have fluted chambers to ease extraction. Round shows
pattern from this. Lockup's up chambering or extracting?

Hmmm... It would seem to be the _best_ option, since all you need to do is
fill the tub, turn it on, and go do something else for a while.

Numbers don't matter much in tumbling... just enlarge the vessel.

I'd soak them in lacquer thinner myself - Then maybe tumble with cork
or something to absorb what is left over. Find the chemical that melts it
off. Turpentine would likely do it as well.

I'd have a concern of having trace inside. That might cause more trouble
than expected.
