Rob, I betcha that's some good to better stuff, never heard of it before, but now I gotta get me some too!
BTW Rob, I got my flashhole liner out without any problems, but the "new one" I found on the bench doesn't have the right threads...no sure why I bought it, or what it does fit, but it ain't the right threads for my Pedersoli...freshened the old one up a bit, added the anti-siege and now I'm good for awhile longer....in fact, visually, I can't see a thing wrong with the old liner.
