Is this a 50 cal? Try the TC shockwave sabots 250gr. Shot some deer with this bullet using 100gr powder and it put a halachious hole in em. I shoot an omega though and at 100 yards its drivin tacs.... I'm guessing you do but your accuracy may be an issue of not cleaning your barrel out every couple shots. I had this prob right away as I didnt know i was supose to clean it so often (was really confused then I read the manual, haha) but now she shoots dead on every time.
