A Bolt’s Kinetic Energyįor small animals like deer and antelope, 23 pounds of energy is the minimum amount of kinetic energy needed. Keep in mind that the larger your broadhead is, the more kinetic energy is required to get good penetration. How fast your bow shoots, the total mass of the bolt, and distance traveled all plays into how much force is delivered upon impact. This matters when thinking about kinetic energy. For example, if your crossbow is rated at 350 fps, it will only travel at about 315 fps if you are shooting a 500-grain bolt. The heavier your arrow is, the slower it will fly. When purchasing a crossbow, the speed ratings are often rated using a 400-grain arrow. A bolt on the lighter end of the manufacturer’s recommendations will fly faster and will give the shooter an extended range but might not get the desired penetration. Keep in mind that even though a bolt will leave the rail quickly, a heavier bolt will quickly lose power as it flies. A heavier bolt, at least 400 grains not including the head, will have better downrange energy and offer better penetration. Now all you have to do is add the weight of the nock, insert, vanes and tip for a total weight. If your bolt is 20-inches, multiply 15 x 20 to figure your bolts weight. For example, your bolt might say 15 grains per inch (GPI). Just about all bolt manufacturers will list how many grains each shaft weighs or how many grains are in each inch of the shaft. The total weight of the bolt includes the weight of the bolt, crossbow nock, insert, vanes, and broadhead or field point. However, it’s hard to think of one good reason why you would shoot a bolt longer than the manufacturer’s recommendations. It is possible to get away with a longer bolt than recommended, but anything shorter than what is recommended could cause the broadhead or field point to get caught on the crossbow rail when fired. Bolt Lengthīolts range in length from 16” to 22”. But, with many crossbows shooting more than 400 fps, the bolts need to be tough enough to prevent them from exploding when shot.

However, when it comes down to it, it’s obviously up to each individual hunter to choose the best crossbow bolt for their crossbow using the guidelines set by the crossbow manufacturer. They will also provide the necessary information for the weight, length, and nock type for their crossbow. Crossbow manufacturers have recommendations for which type of bolt shoots best and these recommendations should be followed. Crossbow bolt length, the weight of the entire bolt, type of nock, and shaft material should all be considered before making an initial purchase.
