TOF - you are A rather amusing individual - as to fouling, as always, I was referring to the buildup of fouling in the bore, which some fellows seem to be troubled with. Of course, there is fouling in the bore after the shot- which is caused by some of the 56 or 57% of the residual fouling after firing off a shot, which as we've tried to explain over and over again, is wiped down when loading the next shot so there is no buildup from shot to shot. Actually, Ned Roberts spoke of this in The Muzzleloading Caplock Rifle. We merely found out what lubes worked as he described - never looked back - never troubled with building fouling- it doens't happen if the ball and patch combo is correct - lubes range from spit to various concoctions.
What we all cannot understand, is why some of you, obviously, yourself included, have to wipe between shots or even after 2, 5 , 10 or 20 shots due to a buildup of this fouling in the bore. Our, and I'm probably speaking of at least the 150 people shoot at Hefley Creek bores don't accumulate fouling. A bore that does accumulate fouoling is either very rough with pits, etc, or is not being loaded so as to prevent continual loading. Try it, you might like it instead of being stuck with fouling buildup.
Your statement about Guiness is interesting - I guess the 150 shooters on the line at the Hefley Rendezvous all need to apply as no one there has a problem with fouling buildup either - it just doesn't happen. Since it is obvious this seems to be happening with your guns, you apparently to fail to 'grasp' what we've been attempting to explain - hense the continual repeating of our process of loading. We do it in an attempt to help you understand that loading this way prevents the buildup of fouling to the point our guns appear not to foul. We've shown and explained as best we can, even did a video some time ago with Taylor loading his rifle after probably 50 shots with easy loading, no hammering. If you want to be blessed with fouing buildup - there is nothing else we can do. Reminds me of a the horse and water limrick.
Are you a member of the Flat Earth Society? - just curious.
