Amazing photo links--really enjoyed. The movie looked dumb, tho. Anyway, the LeMat just had beeswax or other lube over the ball. I gave up on that and now use lubed wads under the ball. They clean and lube the barrel, and do a better job of sealing. I used Crisco over the ball for a while, but shooting blows out the Crisco, so the practice was about worthless. You will find a lot about felt wads and lube, Gatofeo or otherwise, on this forum. And a lot about LeMats, too.
