Dave...I shoot the Penn's through three different revolvers along with several Contenders and have minimal leading in each.

As a note to Bullelk...I was at the range one day shooting my .45LC with 255's (1300fps) when a few other fellas showed up. I heard them comment while we were posting targets that I must have been shooting a .44 Mag for something bark like my revolver was. Since they never directly addressed me I did not feel the need to let them in on the secret of the grand'ole .45LC!
