There is no need to wipe the bore with anything while shooting, let alone potentially.
Why is it that some people try to sell others on the suggestion that black powder needs more than just water for a solvent? I mean - it doesn't even need soap - just plain tap water - and COLD water at that.
Now, the water and alcohol used as a patch lube for pre-cut patches while shooting a winter trail walk is just fine.
Holland and Holland, gun maker of world wide known excellence, since the mid 1800's at least - this high-end English Gun Maker, the Kings' Armorer and Gun Maker, made guns, shotguns, single shot rifles, repeating rifles and double rifles throughout the hayday of black powder shooting, still making guns today - will even make you a new rifle for black powder or smokeless powder, but in ctg. form, for about $150,000.00 if you don't want a fancy rifle, says straight cold tap water is what is best for cleaning their VERY expensive and valuable muzzleloading and breechloading black powder firearms. They've sold you a legacy in a firearm and want you to take the best care of it possible - they tell you to clean it with the best 'solution' there is to preserve this work of art - they tell you to use ordinary tap water, not distilled water or distilled water with chemicals added to it- just ordinary tap water. It's been working perfectly - for well over 150 yards for them and even longer for others, why change now?
I wrote considerbly more, but his will suffice.
The Scheutzen shooters of the late 1800's and 1900's had a bucket of water, with a slotted rod with patch sitting in it. It was for wiping the bores of their bullet shooting black powder ctg. guns that needed wiping, between shots due to fouling problems with ctg. guns - an old problem that dated into the muzzleoading theatre of the mid 1800's. There was no patch to wipe the bore clean, as you loaded it for successive shots.
A round ball muzzleloader, expecially a hunting-type muzzleoader does not need wiping during shooting to maintain accuracy. Many bullet shooting muzzleoloaders don't either, but require specially designed lubricants. There are many people on this site who never have to wipe their bores while shooting - the 60th shot loads as esily as the first nothing but water - in the interest of making this sport as enjoyable as possible, the info is free - of course - nothing to buy. To- - a bonus, is that these shooters are probably the best, most experienced and most accurate shooters here.
