hot soapy water, the hotter the better, then lay the barrel on the wood stove overnight. old hillbilly method. load and hunt or oil and store the next morn.
Well, everybody cleans them a lil different, but IMHO if you wait to oil that barrel, the bore has already started to rust.............
You clean that barrel with hot soapy water & dry it & not imediately oil it ? within 30 minutes it will have flash rusted & overnight it will have rusted & etch the bore most likely..... Happened to me on a barrel about ? 1979 or 1980 I guess.
Here is a test you can do. Take a piece of Bp rifle barrel & saw it lengthwise to split the bore. Clean it really good in hot soapy water & dry it & just put it under a microscope & watch the rust start to form in about 10 minutes. (Do it outside when it is humid out & you can actually See the rust start with the naked eye in 10 minutes) Now go back at 30 min, then go back every 2-3 hours & see what happens. By 24 hours it will be etched & it will take 2-3 days of bore lapping to get it out, IF you ever do get it all out.........
You can clean one with Hot or Cold soapy water, but you better dry it Good & Oil it "Right Then" if you don't want it to flash rust...... Then swab it again the second day & again the third day..... I prefer cold water but some guys like the hot water method. Main thing is you get it clean & dry before oiling.
You would be simply amazed of how many emails I have gotten over the past 10 years of guys wanting to know how to get rust out of the barrels because they cleaned them & didn't oil them well or didn't go back the second day & reswab them. I am not talking about on or two, I am talking about dozens of inquiries......
Dn't take a chance on the bore.........be safe, clean it, dry it & OIL it........ If you are going to hunt the next day it takes all of 2 swabs (2 minutes) to get the oil out of the bore.......
