hey goose welcome to the boards, i like t/c products, i have shot the omega and i own a black diamond and have a encore with a 209X50 barrel for it, both are capable of 150gr. charges but all i ever shoot is 100 using 2 pyrodex pellets, my grouping is better and the gun dosen't kill on both ends, plus shooting 150gr. alot of the powder is still burning going out the end off the barrel, as far as moose i'm not sure, someone on here will be able to help you with that though, but as far as the t/c products i don't think you can go wrong, best of luck
