As the title says finally got tired of arguing with the nervous nannies at our gun club.
I started muzzleloading in the 70's and everyone that I shot with (at this same club) blew down the barrel and used spit patches and I have been doing it and (back when I could see) winning matches.
For those that do not know, the moisture in your breath keeps the fouling soft and a spit patch wipes the bore on the way down and even with a tight ball and patch combination (think short starter) you can still shoot all day long. If you question this, find a BPCRS shooter and ask him why he uses a blow tube (although bore pigs have some proponents), and if he's not using one or the other his scores suck.
After forty years the only damage the empty gun has ever done to me was sometimes I noticed that my lips were black on the way home (wondered why the waitress looked at me strange).
Anyway her is my solution

7/16 OD vinyl tubing with some white duct tape wrapped around it. So far, I have used it on a .45, .50 and a 54 and the duct tape has enough wraps that it has sealed on all three of them.
Personally I regard it as an unnecessary evil and will not use it unless at the bench and the nannies are singing their song, (you know the one "You'll put your eye out" .
Hate to let them win but I am pretty sure Simon Kenton had vinyl tubing so there you go.
