I do not believe that gunpowder residue and bore oil creates any type of coagulate, or substance that can build up to dangerous levels. The sealing of the wad, whether it is fiber or poly, is enough, IMO, to wipe the bore pretty doggone clean after each shot. Even the shot load itself, in the case of a "naked" payload which has no shot wrapper preventing it from contacting the bore, would remove any previous deposits, with the exception of leading and maybe some plastic buildup. In high volume shooting, like 1000+ rounds in three hours, I've never seen buildup become a problem in the bores. Chambers are a different matter, as plastic will build up to the point that the gun will start ejecting the hulls sluggishly or not at all, and require a quick chamber brushing to restore function. What you see deposited there in the bore is from the previous shot. I have never wiped the bore dry before firing a shotgun, but will own up to not using large amounts of bore protector. I feel a film is all that's needed. Rifles, and muzzleloaders are exceptions. I always wipe them dry before shooting, even to the point of pouring alcohol down the bore of the m/l and letting it run out at the breech to dry it completely of oil, but that is to prevent a misfire, not for safety sake necessarily.
I see varying amounts of residue in my shotgun bores, from different shells and loads, but never enough to look anywhere near dangerous. I'd like to see what that looks like in your barrels, from the RSTs. Wish you could take a pic and post it.
