At the casting bench in the sky. RIP Bret.
I leaded a lot of barrels trying rock hard cast at 2K+ speeds. I found plain old ATF/MIneral spirits (or even diesel!) and 4/0 steel wool worked good for me.I wonder...
What would an ultrasonic cleaner, long enough for a barreled action, do to old, neglected bores or leaded bores?
Fortunately, I haven't had one lead up very badly in many years, but I remember some some factory reloads in the eighties, which would completely obscure the rifling in a couple of my revolvers after very few rounds. Spent the rest of the weekend mining lead with a Lewis lead remover and a "lead remover cloth." That got very old, very quickly.
