Except that nowhere does the OP state his zero range and the question was how much would the pellet drop? .
30 yards is a close zero to be using with a 32fpe gun, each to their own, but it would reduce the amount of holdover required by using a more distant zero. Ideally use a zero for the range being shot over.
for the benefit of 3 wheeler (its easy if you want from barrell just subtract 2 inches from what i stated before).
its 2 inches from my scope to my barrel so take 2 inches off the total drop if you want inches drop from muzzel to down range point of impact. Note 3 wheeler that this is my setup and others might be different from different barrels.
