theres more than 1 way to skin a cat as they say. each method has pros/cons. mfgr's say to foul it. PRO'S: likely drier and a higher chance of ignition, CONS: how corrosive are primer powders? many people leave fouled mzl's loaded all season (maybe til next season) and just remove the primer,will that fouling be eating bbl metal the whole time?, fouling will attract moisure.primer residue not as corrosive as burned black powder or b/p substitutes (I believe) and I'm sure all are diff. but if you fire the fully loaded gun it really should be cleaned within a "reasonable" time.#2 PROS Allens method of the brake cleaner will leave the bbl and parts clean and dry. not sure if it leaves any residue/film that may attract water (let's say no), if intending to hunt with it in a day or 2 I see no real need to oil it at all and you will get that True FIRST shot. CONS: not everybody makes 1st shot neck hits like you, what about the 2nd or more shots? depending on the gun and load each shot from a fouled gun should be pretty close for I'd guess 8 shots anyway, certainly more than you should ever need.
one of the good things about b/p is you don't normaly need harsh chemicals to clean them. a 5 gal bucket with 6-8" of hot water and some dish soap should do it. plunge the bbl right in there and scrub away. if you get copper or plastic build up you MIGHT have to use something stronger but if you clean it within 24 hrs of firing I'd say no, I've never had to. clean-green, hug a tree while youre at it.
When I shot old school m/l's, that is the way we cleaned them. Now with scoped barrels, it is not quite as easy. Can be done, but you gotta be careful not to fog up the inside of your scope
Come to think of it, that may be a good option for the OP since it does not have a detachable breach and more than likely is not scoped
my bbl goes in the bucket scope and all muzzle first. I swear by those butler creek flip open scope covers, they really work. saved my leupold, didn't open or let in mud when i took my little drainage canal swim. all the other parts go in the bucket too: timney trigger,breech plug and bolt, actually a faster and better clean than my bolts/lever or semi.
an fyi, hornady makes "one shot" a spray on dry lube that will not affect primers or attract crud. I don't think it lasts as long as wet lube but gets the job done fine while it lasts. for most stuff and long term my current fav is break-free.
