Arrow weight is the only factor that you can directly control to change your crossbow’s speed. A light arrow is easier to move from rest than a heavy one, so your crossbow will shoot a light arrow faster than it will shoot a heavy one. When a crossbow transfers the energy stored in the bow assembly to the arrow through the string and accelerates the arrow down the flight rail, it delivers the same amount of force to the arrow when it launches it each time. TenPoint’s Wicked Ridge Rampage 360 crossbow utilizes the same stock, flight rail, and bow assembly configuration as the Invader 400, giving it the same 13.5-inch power stroke, however the string on the Rampage 360 is mounted at 175-pounds, thus yielding a speed of 360 feet-per-second with the same 370-grain arrow.Īrrow weight is the third, and perhaps most important, factor that determines crossbow speed because it is the only one of the three factors that you can directly control with your crossbow arrow choice. If you have two identical crossbows with the same power stroke but the string on one is mounted at 10-pounds heavier draw weight, it will shoot faster than the one with the lighter draw weight because the force of acceleration is greater.įor example, TenPoint’s Wicked Ridge Invader 400 crossbow has a 13.5” power stroke, a draw weight of 185-pounds, and shoots a 370-grain arrow at 400 feet-per-second. ![]() The draw weight of a crossbow also factors into its speed. Reverse draw crossbows have a power stroke advantage over forward draw crossbows. This is why reverse draw crossbows have an advantage over forward draw crossbows. ![]() ![]() Generally speaking, crossbows that have longer power strokes will shoot faster than crossbows with shorter ones because the string accelerates the arrow for a longer distance. Power stroke is the distance, in inches, that the string accelerates an arrow down a crossbow’s flight rail.
