Home Blog How To Choose the Best Crossbow Bolt Weight

Crossbow bolts come in many different weights that range from lightweight to standard weight to heavyweight.  You may have wondered – why are there different crossbow bolt weights and what is the best weight to shoot from your hunting crossbow

Lightweight crossbow boltsLighted Pro Elite 400 Carbon Crossbow Arrows weigh-in between 350 to 399 grains, standard weight crossbow bolts range from 400 to 459 grains, and heavyweight crossbow bolts weigh-in at a hefty 460 grains and above.  These bolt weights include the weight of a standard 100-grain field point in addition to the weight of the finished bolt itself.  In other words, when we say the overall weight of a crossbow bolt is 400 grains, what we actually mean is that the finished bolt without the point weighs 300 grains and then you add the 100-grains from the field point to arrive at the overall weight of 400 grains.

3d Shooting Vapor 900 X 900For you to decide which weight is best for you to shoot, you must consider the scenario in which you are shooting.  If you use your crossbow for competitive shooting, like 3D archery, you should choose a lighter bolt that travels faster.  The faster a crossbow bolt travels, the “flatter” the trajectory it has as it is flying to your target.  This means if you misjudge the distance to your target, a lightweight, flatter shooting bolt will drop less fast and you will miss your mark by a smaller margin than if you had used a heavier bolt.  Archers often refer to lightweight crossbow bolts as being “more forgiving” for this reason.
