Never personally had good results with Powerbelts, and have two friends who would have them keyhole down range on the paper. One even swapped over his .50 cal to the .45 barrel that it came with and had some **** poor grouping. You need to find a bullet that works for you and your gun.

Shockwaves are all I shoot out of my .50 Hawkens, .50 CVA, and .45 CVA. Would shoot them out of my 1851 Navy .44 BP pistol if they made them. They just work perfect for me.
