Get some Ballistol.
You can use it staight or diluted to clean the barrel and then swab the bore really good with it straight to prevent rust.
If you do the bucket thing, swab the bore good with a well-soaked straight Ballistol patch or bore swab. Even if you failed to get all the water out, Ballistol will mix witn the water and still protect the bore.
You can even put it on your boo-boos, although in the U.S. it's not approved for that.
I love Ballistol, that stuff really gets the bore clean. I used to think it was a hoax until I tried it. Dont know if I could use it straight tho, that stuff friggin stinks! But it sure works great on BP.
