Daryl, how many times do you push a single patch thru the dirty barrel to get it clean? Do you rinse the patch? Or does the pumping action of the water do the trick without changing patches? I don't submerge my vent in a bucket because I do not remove my barrel from the stock--I might do that once a year, or after a particularly wet snowy outing?
I remove the lock and barrel from the stock. I clean the lock in the water in the coffee can using a toothbrush on the fouled areas. I find if I don't scrub the bearing surfaces, the moly grease I have on those will remain for up to a year. I blow off the lock, wipe it down, then spray if all over with WD40 - shake it off, and set it aside until I clean the barrel.
I then put the breech end of the barrel in the container of water - lately that is a red plastic Folger's Coffee can. I use one patch and pump/suck water into the bore all the way to the muzzle-end of the barrel, then push hard, flushing that water and fouling into the container. Suck/flush/suck/flush - maybe 20 times. The patch itself will be only slighty greyish by the time the barrel is clean. Then, out of the cold tap water, wipe off the outside with a towel, then run a folded flannelette patch to the bottom of the breech, then out, in and out again, then change to another. By the time the 3rd one is used, the bore is both clean and dry. Then I spray copious amount of WD40 into the bore until it dribbles out the vent or nipple seat doesn't take as much as you might think, but at $30.00 per gallon, the gallon will last a couple years if you shoot a LOT. I then take a new patch, double it and run it down to the breech- hard, this will blast excess DW40 out the vent or nipple seat - up, down, up, down and then use that patch to wipe down the outside of the barrel.
I then blow the excess WD40 off the lock with an air hose or can of compressed air. Reinstall lock and barrel and done. It takes about as long to type this out, than it does to clean the rifle. Maybe 10 minutes at the outside. Been doing it this way since the 70's.
I have NEVER had a bore rust after being cleaned this way, but then, I've never used Balistol.
2 guys I know very well tried it and BOTH had rust in their barrels the next morning. I would question using a water soluble oil as a rust preventative.
