Sabot, I use Pyrodex RS. I know water is attracted to it which is a primary reason to unload the gun. I wonder if the old timer you know has greased his barrel by using bore butter or another lube. I've heard a gun can be "seasoned" that way. After all, it seems unlikely our frontiersmen unloaded their guns while in hostile indian territory or grizz country.

Cayugad, it's comforting to hear you condone this procedure for unloading. I'm going to post a couple of other questions now.
