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
