I had my mind set on 100 grains of pyrodex powder in 2 5o grain pellets. With a 295 grain powerbellt aerotip bullet. The more i read about powerbelts exploding and not finding the animal the less confident i feel about them. I have a CVA OPTIMA 50 CAL. 1:28 inch twist. What would be a good bullet for this it willl be used for deer.
