I have shot many deer with the power belts. I also use the 295 grain hollow points and 100 grains of triple seven powder and i have no trouble killing a deer from 100 to 200 yards with this combo and it is also very accurate. I to also shoot a cva except mine is a Cva hunterbolt. Also if you find that it is not accurate at 125 yards add a little more powder to the combo.
