How many....

Not me. Why would one do that?

Because he is doing everything else wrong!

That destroyed patch is caused by one or more Failures of his system or components. Eg., patch too thin, patch too weak, bore rough, and more. When the load is tight enough with a clean crown and a clean smooth bore and a strong material, the patch isn't going to burn up or be wrecked. FWIW, that last patch he shows off doesn't look good at all. It shows shredding right up to where the ball contacts the bore. That can indicate the patch is too small.

Here's what a tough proper fitting patch fired from a rifle with a clean crown and smooth bore looks like. Oh, and lube? I get the same results regardless of lube. Probably the same with a dry un lubed patch.

I use a pinch of corn meal on top of the powder. Before I started doing that my #40 pocket drill or any other patch was shredded beyond recognition. No matter what lube or charge I use.
I tried cleaning up the lands at the muzzle and working the bore a lot with 4/0 steel wool and Scothbrite but nothing worked until I started putting a buffer under the ball.
My patches are now almost reusable.
I haven't shot without a buffer with my newest rifle so it may shoot fine without it.
But to answer your question I've never tried a patch

I tried using a leather over powder wad with heavily greased mini's to prevent the grease from fouling the powder while deer hunting. I liked the results and tried it with patched round ball and found it improved accuracy.

I've been shooting these things since the '60s and found no reason to shoot an over power patch.

I recall Idaho Lewis saying if you are burning patches use a over powder patch to stop it and improve accuracy? Not an exact quote but close!

With all due respect for Idaho Lewis's shooting achievements, which i think are amazing, patches that burn up are indicative of other problems.

I think you are refering to to much powder? I am not sure what the problem is but it very well may be in order to shoot a heavy load not normal for the rifle a extra patch on the powder may be a cure? It just might improve the seal when two patches are used? I am sure someone will know what the deal is. I know I use one patch holding the ball and accuracy is better than I am?

Sam Fadala covered this years ago. It helps if a rifle is blowing patches. I prefer to find the right combination and use that, rather than the extra step of putting in another patch.
