Loaned my trusty .32 squirrel gun to a friend for a few weeks and when I got it back the bore was full of a fine powdery rust. Ran a cleaning rod down the bore and could hardly get it all the way down due to the rust. My friend claims he cleaned it well. I don't doubt him for a minute as I've seen him clean his rifles and also seen many a rust rifle in his cabin
So I asked him how he cleaned blackpowder rifles. (Seems like everyone has some kind of overcomplicated cityfied formulation for the simple cleaning process.) He uses factory lubed patches. Here is what he told me:
"I swipe the bore between shots with a hydrogen peroxide mixture to keep her clear of residue, then after a day of shooting I clean her up good using a good bore cleaner, some denatured alcohol, some 3-in-1 Oil, then swipe her down a few times with WD 40, and finally swab her clean and then apply some Breakfree." He said he always has a problem with rust.
I was amazed, as I lube my patches with good old Upper Cumberland Spit. Works just as good as any of those other high-priced commodities! Then after shooting, I'll run several patches down the bore and clean the lock just a little with cloth patches and USGI CLP (Breakfree- cleaner, lubricant, protective). If I'm going to be shooting in the next week, that does pretty good, but if I think it will be much longer than that I'll mix up a batch of warm soapy water (not hot) water and clean her good. The next couple of days I'll run an oily patch through just to make sure she's cleaned well. That has always worked and I've never had a speck of bore rust. I just wipe down the outside of the barrel with a dry rag.
Anyway, I can't get this bore to stop rusting. Every morning for the last two weeks I've run an oily patch down the bore and it comes out discolored from rust. I've even tried baking soda to neutralize the peroxide- don't know if that made any sense, but I'm a desperate man!
This squirrel gun had over a 1000 shots fired through her and the barrel was seasoned like my Granny's best cornbread skillet! Now it's just a heavy rust producer!
Somebody tell me what to do!
