ML. I shoot a T/C .54....Love the gun by the way. I switched to .295 Powerbelts with 100 grains of 777 some years ago and have had very good results. I have seen some people post issues of powerbelts "sailing", but I have never had that issue, I can keep a 2-3" group at 100 yards. Some opinions may vary about the knockdown power of the .295, but I have never had an issue. If the shot it true they perform just fine.
