You decide to try out some new, heavier, expandable broadheads, thereby increasing the weight of your arrows to a total of 450 grain – a 50 grain increase. ![]() As a general rule, assume a 1 (one) FPS shooting speed difference for every 5 grain of arrow weight difference – the heavier the arrows, the lower the FPS, and vice versa.ġst Arrow Drop Example: You’ve been shooting 400 grain arrows at a speed of 300 FPS. The numbers above should help you stay aware of how important proper arrow selection is to keeping your shots on point, and how important re-sighting your crossbow is when switching between arrows of different weights. How Can The Arrow Drop Values In Our Chart Help You? The chart below, the values displayed within it, and the research conducted is copyrighted material and is the property of You are welcome to share it, as long as you mention our website as the original source of the data / research. Based on the results of these tests, the interactive chart below was created. The actual arrow drop was then manually measured at 15, 20, 25, 30, 35, 40, 45 and 50 yards for each shooting speed configuration. The crossbows were sighted in at 10 yards (due to indoor shooting range size limitations and because the goal was to get as many readings past zero as possible) and then multiple arrows were shot at each different speed setting. Arrow weight and crossbow configurations were manipulated to achieve varying shooting speeds, ranging from as low as 200 FPS all the way up to 400 FPS. In order to figure out exact crossbow arrow drop, we ran a series of extensive tests, conducted by ballistics professional of 30+ years and avid archer/hunter Kim Lockhart of, using more than a dozen different crossbows. ![]() Also, make sure to check out our Kinetic Energy Chart for more information, and our best crossbow rankings if you’re looking for a high a solid crossbow. But how does this relate to crossbow arrows, exactly? Let’s find out. The laws of physics dictate that what goes up (or forward, for that matter), must come down.
