Yeah, I thought about putting some kind of stem in there that would go up into the 25 ACP case. But after shooting another 25 shots Saturday with the new plug in my Mustang, I just don't think it's worth the effort for the little that may be gained - and the plug would probably be a lot harder to clean.

After twenty shots with various loads of T-7 and five shots with JSGthe plug unscrewed as though I had just put it in. So little fouling in the breech area that Ijust wiped it off with a paper towel dampened with Butch's Black Powder Bore Shine, then a little light oil. Cleaned the plug and barrel real well, followed by a light coat of oil - done.

The only thing I do want to try is that teflon tape method some NUT is touting these days.
