There is no need to wipe a revolver's bore IF you use a stiff, felt wad --- properly lubricated --- between the ball and powder.
A proper wad, with the proper lubricant, will wipe the bore almost free of fouling with each shot. This cannot be said of Wonder Wads, with their dry lubricant. The felt wad must have a grease-type lubricant, and it must be a particular type of lubricant.
Crisco won't do it: too soft. Beeswax is okay but lacks the moistness required to keep the fouling soft.
Here's the recipe I found in a 1943 American Rifleman magazine that is, by far, the best lubricant I've found for lubricating felt wads:
1 part canning paraffin (sold in the grocery store)
1 part mutton tallow (sold by Dixie Gun Works)
1/2 part beeswax
All measurements are by weight, not volume. I use a kitchen scale to measure 200/200/100 grams of ingredients, which all goes into a quart, widemouth Mason jar.
The jar is then placed in a small pot of boiling water, four or five inches deep, for a double-boiler effect.
When all ingredients are melted, stir well with a clean stick or disposable chopstick. Allow to cool at room temperature; hastening cooling by placing in the fridge may cause the ingredients to separate.
You cannot substitute the above ingredients. Doing so will result in an inferior lubricant. Mutton tallow is better than lard, Crisco or any of the game (elk, deer or bear) tallows for this purpose.
The above lubricant is a wonderful black powder lubricant for all applicaions: felt wads, patches, bare bullets and over the balls in cap and ball revolvers.
A felt wad soaked in the above, when placed between the ball and powder (in rifle, pistol or revolver) will keep the bore rather clean shot-to-shot.
I have my own theory about this. I believe that the addition of paraffin stiffens the felt wad somewhat, making it a more effective fouling scraper. I've tried other lubricants with felt wads and the above recipe is clearly the best. It's also excellent for lead bullets loaded in black powder cartridges, such as the .44-40 or .45-70.
There's no need to wipe down a revolver bore with each shot. If you're only loading one chamber at a time, to determine which chamber is the most accurate, I suppose you could.
But better still, load a stiff felt wad with the above lubricant between the ball and bullet. It will keep the bore rather clean, with little more than a fine black ash. Most of the fouling will be pushed out by the greased wad.
