Use this calculator to ESTIMATE the most efficient TOTAL arrow weight for your crossbow setup based on current initial speeds, total arrow weight best found using a chronograph and a calibrated scale.

NOTE: This calculator uses a 1 fps drop in speed for every 3 grains increase in arrow weight.
NOTE: Due to rounding some of the values could present as being the same.
