set up: knight dics, 100 pyro pellets.
ive been using powerbelts with so/so accuracy. i want to swith to hornady xtp or go back to knight sabots. so far i have found 240,250 and 300 grains. which is best for hunting whitetails? the only thing i like about the powerbelts is i can start them faster in the gun. i was using the 295 grain.
all you bp shooters, please help.

thanks
