Ok, my 2 cents.
First of all, if the muzzle is clean, and NOT tearing patches, I’ve never seen any need to use a wad over a patched ball.
If the patches are not tearing, they are burning through.
This can only mean 2 things…….
One, the patch is too thin.
Two, not enough, or the right lube.
Not sure which of these are the issue, but make sure all three are right, and forget about a wad under the ball.
