I bought a .50 cal wad punch as I had been told they work well in an Old Army. I punched several out and soaked them in my Gatofeo's #1 lube, and tried them last week only to find that they do not work.

I informed the maker that it does't work. He stated that he'll be sending me a new one at no cost. I believe I am getting a Lyman's .50 cal Deerstalker for Xmas, and asked if it would work in it, that I'd pay for the new one as well, as I don't want him to be out his materials and time. He has not replied.

I know it won't seal the bore, but if it were used behind a PRB or a conical does that really matter? It seems as though it wouldn't clean out the grooves, but it may help scrape some fouling off. Or would it likely push it into the grooves?

When wads are used and help with a load's accuracy it's because it does seal the bore and adds to the pressure correct?

I'm not certain the exact diameter, but I believe it to be .500", and the lands on a Lyman are .502" according to the pdf.
