I was using the power belts out of my optmia elite with 110gr of powder. I only shot 1 deer with this load and it worked well, but the fellers in the blackpowder forumenlightened me that these bullets would fragment with this load and suggested that i lower my powder down to 80grs. This load shot so well i hated to lower my load and because sometimes i need to shoot at longer ranges. So i switched to shock waves 250gr bonded bullets. I shot a 8pt early this year and it performed perfectly to, a complete pass thru and the blood trail was perfuse. I know that you cant tell how good a bullet will be from just one kill, but the SW got off to a good start. I have muzzleloaded since I was 16 years old, but I have just started using the sabots the last couple of years, I have always used TC maxi's and super slugs out of my white shooting system rifle. GOOD LUCK
