Thanks Max for the recommendation of using power pistol with cutting edge bullets a few months ago!,I was loading some .40 S&W with it yesterday and decided since I have it in the hopper might as well try it with some 240 grain raptors in my .454.WOW is all I can say! After almost giving up on the copper with this I hit the jackpot!1610 fps and 1-3/4 inch groups (3shots) at 100 yds.I might tinker with the weight a little-18 grains but this is it!! also very clean burning!!,thanks again and happy new year to everybody!
