RonT.One thing to watch out for in your cleaning method is that water gets under the bridge that is between your ramrod and barrel. Years ago I found Ihad significant rust build up under it.

Thanks for the "head's-up", S.S., but I use VERY hot water and then BLOW out all the liquid using 100 lbs of air-pressure from my air-compressor. Even after I blow out all the liquid, the barrel's steel is still very warm.
And so, I doubt that there is any liquid (aka "water") left anywhere in the bore and flash-channel... but I appreciate your thoughtfulness in warning me about the problem you had.
