Most recent trial and SUCCESS was transforming the New JSB HADES hunting pellet into a heavy weight hunter for my .20 cal air wolf.
15.9 grains of whoop ass smack down power for the heli-board Daystate Air Wolf ... Can shoot these easily into the 900's with very good accuracy shooting just like 15.9 domes did. .22 HADES on Left and resized to .20 HADES on right. Die is self made with pellet driven threw the die with purpose made punch .. one hit and pellets out the bottom of die and ready to shoot.
