![]() Arrows with a heavier FOC will do more damage and penetrate deeper but will lose accuracy over distance. The Front of the Center is important because it determines the trajectory of the arrow, which in turn determines accuracy. The FOC stands for “Front of Center” and is the percentage of weight focused on the front half of the bolt. Bolt length is an essential factor in the FOC. What About Bolt Length?īolt length plays an integral part in this equation, from the total weight to the speed of the bolt. Bolts are available up to 400 FPS, but generally, hunters prefer their speeds between 300 and 330 FPS. It is simple physics that an arrow that travels faster from point A to Point B will also travel straighter. The other part of the equation that makes FPS so important is accuracy. Many argue that the few milliseconds of difference don’t matter, while others believe it is the difference between a kill shot and a grazing wound. ![]() The general idea is that your arrow must travel faster than the speed of the sound your crossbow makes as it will alert the prey of your presence. Many veteran crossbow hunters will tell you that FPS is third or fourth on the list of most essential features of a bolt, but it is still important. The give or take of 100 grains won’t be noticeable in your hand, but it will be observable in function. One ounce equals 437.5 grains, so the most common weight of an arrow is one ounce. ![]() The difference between a 300-grain bolt and a 500-grain bolt may sound like a lot, but you wouldn’t even be able to tell the difference between the two if you held them in your hand. If you find yourself wondering how much damage your bolts will do, you can use a kinetic energy calculator to get a better idea. So, if you buy a box of 300-grain bolts, they will be much faster than the box reads, and if you get 500-grain bolts, they will be noticeably slower than what it says on the box. A lighter arrow will give you more FPS and better accuracy but not do as much damage making these bolts perfect for small game hunting.Īnother notable fact is that the FPS on a box of bolts is always based on 400-grain bolts. Heavier bolts do more damage and penetrate deeper than lighter bolts, but they also don’t fly as far and lose accuracy over distance. Most people like to be in the early 400s range because it is a median weight that balances the pros and cons. The deciding factor for the weight of your bolt comes down to personal preference, but they both have their advantages and disadvantages. ![]() When would you want a lighter or heavier bolt?. ![]()
