There are certain things that you need to be conscious of before you head out and purchase arrow/bolts for your crossbow. For beginners, you should know that you are running the risk of sacrificing your accuracy and you could damage the crossbow if you deviate at all from what the manufacturer recommends. You will get different arrows, than the ones that have been contained in your package, just make sure that these are typically built to the same specs.

One of the primary items that you need to know is you certainly will require an arrow that can create 30 ft./pounds of kinetic energy to entirely penetrate that sought after buck. You will need 50 ft./pounds for something that has a thicker hide, such as a moose or bear. The industry standard for ratings speed (and hence determining kinetic energy) is making use of a 420 grain bolt during tests, and that means you should always keep that at the back of your mind.
Then it would seem like common sense to assume that lighter bolts fly faster than their heavier counterpart if you are on the outside looking in. This really is true, but you can find many other factors that may affect your arrows flight, below you will find these broken down in detail.
The concept that is first you should take into account is the crossbow arrow spine. That is in essence, the backbone of this arrow. It will offer the person shooting aided by the perfect balance of stiffness and flexibility. Since an arrow flexes when it is shot from a weapon, you'd need to know its back. The manner in which you plan on using the arrow will greatly push your decision a proven way or the other. Luckily for us, crossbow arrows are short enough to where they wouldn't necessarily require a specific arrow spine. Since the arrow won't have to flex around a riser, but rather it glides along the rail, you should be fine. The factor that you need to be more focused on may be the diameter (inside and outside). It's also wise to verify to decide on the correct arrow that is total (with the tip connected)
Crossbow Arrow Bolts will typically always have a larger diameter. This is because the larger diameter helps with the back. They likewise have a much heavier load to bear given the draw weight on even the most standard of crossbows. The most widely used at the moment are .013 if you work with Aluminum Arrows .016, .019 for shaft wall depth. The carbon arrow has taken over due to its consistency in recent times. The most popular diameters in this category are 21/64'' and 22/64''
You have to make sure that you follow the instructions that are provided from your manufacturer when you are looking for arrows. The unit of measurement for arrows is in grains. Depending regarding the draw fat of your bow, you should have a certain minimal arrow weight. For the most typical crossbows that are on the market I have not seen recommended grains below 350. They usually hover around the industry standard of 420 grains. I have a preference for a heavier arrow, because it assists to lessen the vibration and noise a bit also. It should also be noted that the heavier arrows will tend to make the crossbows slightly more efficient, while the lighter arrows is likely to make them less efficient.
Arrow Shaft Length
It's also advisable to take note that the size of your bolts will affect the dynamic arrow back. Think about it in this way. It is actually being compressed when you shoot an arrow from your crossbow. The string is pushing up against the arrow and force that is putting it. If you have an arrow that is longer, it will inherently be easier to bend. Today again, we are lucky because you will typically only need 20'' Crossbow Arrows or 22'' Crossbow Arrows given the industry standards for crossbows.
The fletching are the tiny items of product that you will typically find during the straight back of the arrows. People consider them become the wings for the arrow along its flight path because they help to guide it. The fletching helps you to support the arrow by causing the arrow to spin during its flight. You will commonly hear the definition of vanes whenever people reference the fletching on the crossbow arrows. Almost all of the vanes for crossbow bolts are produced from some type of durable synthetic. There is no standard for which type of arrow vanes you should utilize, but it is a general rule that the longer your arrows are, the bigger your vanes must certanly be. 2'', 2.5'', and 3'' are the most common you will find for crossbow arrows.
Type of Nock
The nock may be the portion associated with the arrow that is found right behind the vanes, at the final end of the shaft. Its purpose would be to keep the arrow in place on the string as you fire. There are two types of nocks that you shall see when looking at these kinds of arrows. The initial, and a lot of common, is the half moon nock. These have one end on them that looks like (you guessed it) a crescent or half moon. The groove is used to carry the arrow in position on the string. Flat nocks are one other form of nock which you will find on the arrows.
FOC (Front of Center)
This concept is important because the front of center of the arrow is going to influence how it fly's. It becomes increasingly important, the further you are from your target. Additionally it is important to note that utilizing various kinds of broadheads will affect your arrows flight. There is certainly a great deal of confusing jargon associated with this term, but a very important factor you'll want to know is that if you are a hunter, you will require a higher FOC because you will require to get the many energy from your own arrow to your intended target. Having a bigger FOC will even absolutely affect your arrow flight. The recommended FOC for an arrow who has a broadhead tip is usually in the 10-15% range, with some even recommending FOC's as high as 30%. We will dive a little bit deeper on FOC, in the article that is following.
