Johnny, I use them exclusively now. I shoot an old knight wolverine 50 caliber with the #11 cap. I am shooting the 220 grain dead center and 80 grains of 777 ffg. I had terrible trouble with the 300 grain hornady xtp's (although I know a lot of people love them). They shot great but didn't seem to do any damage to the deer I shot. They would run forever. I was at the point of giving up ML'ing until I found the dead centers. Here are a few pics of the dead centers I have recovered from the deer I have shot, none have gone over 30-40 yards. See what you think, Greg
