Hank, one of the two bullets I use is a 'Keith style' commercial. The other is a home cast WFN. Neither have the gas check you prefer. I don't find leading to be a problem and use these same bullets in my Ruger .45colts to 1050 - 1100 fps.

Craig, 1100 would be more than enough for the critters I hunt. Not sure how well lead bullets and the comp will work together. The only 'comped' handgun I own is a 'tender 14" .45-70 and I shoot 'jacketed' in it.
