good evening everyone I hope things are going well for you. I have 2 t/c/ smoke poles. 1. t/c/ 50cal encore and 2. t/c/ omega 50cal. I have been hunting with the omega since I got it. I am going to take both to the gun range soon. I have read a lot on sabot,s and powder,s. I have shot the the power belts and I am not happy with them at all. the DO disintergrate just inside the entrance hole. the exit is the same size too. so I am into moving to a sabot and blackhorn 209 powder. but am unsure on how to convert volume to grain weight. I love shooting my omega and would like to start shooting the encore. and comments on sabots and or powder I would like to read. thank you all and hunt safe and shoot straight. jim
