Me, I usually shoot a string of pellets from a known psi to known psi. and with my Prod, I started out high like 3000psi and found the fpe leveled out about 26-2700 psi. so the next string I started at that point and most of the other pellets tested from that pressure seem to be right on.
shooting with different pellets on the same fill doesnt seem like it would get any thing because as the pressure drops the difference in pellets would affect the results. so shooting with one pellet, than another on the same fill, till you find the sweet spot of all pellets tested.
