Ballistics of crossbow arrows

There are two main factors influencing ballistics - the weight and stiffness of the arrow (of course, provided that the arrows themselves are straight). Everything is clear with the first one, since it is reflected in the fundamental formula E = mv2/2. That is, both speed and energy depend on the mass of the projectile. All this significantly affects the flight trajectory, and therefore the accuracy of the hit, the calculation of aiming corrections, the firing range, etc. It doesn’t matter whether it’s a bow, a crossbow or a rifle.

This is what the real speed indicators of one crossbow with original and GOST shoulders look like for various arrows:

Necessary explanations for crossbow-bow units of measurement:

1 Lbs (lb) = 0.45 kg

1 grain = 0.0648 grams

1 fps (feet per second) = 0.305 m/s

The issues of dependence of arrow speeds on the types of arms and other factors are discussed in more detail in the article “Powerful crossbow - what kind of animal is this?”

For uniform ballistics and, therefore, high accuracy, all your arrows should be the same. Uniformity will also help avoid additional shooting. With an average weight of an arrow with a tip of about 25 grams (390 grain), we are talking about tenths of a gram. Almost any household electronic scale can easily cope with such measurement accuracy.

Much more difficult with rigidity. An arrow is not a bullet; in flight it wriggles like a snake. This phenomenon is called the “arrow paradox” and is often played out in Korean and Chinese historical action films, when on the screen in slow motion arrows manage to cleverly go around “their own” and hit the enemy. We will dwell on it in detail in the article about archery arrows, since it is difficult to do without adjusting the rigidity (“spine”) to a specific bow. “Spine” is the amount of arrow deflection in fractions of an inch. For example, with a spine of 400, the value is 0.400 inches (2.54 cm).

In short, the spine measurement technique looks like this:

The load must be a certain weight (880 g), the boom must be 29 inches long, etc. The smaller the “spine” - the amount of deflection of the arrow - the stiffer it is. The length of the arrow, the weight of the tip and shank, the strength of the bow, and much more are also taken into account.

For a crossbow, this factor is not so significant. The fact is that a crossbow arrow is much shorter than a bow arrow and in any case, even with relatively thin walls of the “tube”, will be stiffer (archers cut the tubes to increase rigidity). In addition, unlike any bow, it moves along a guide groove. And yet, “spine” cannot be completely discounted. Simply put, the more powerful the crossbow, the stiffer the arrows should be. And the larger the animal you are going to hunt, too. As, by the way, is the total mass of the arrow with a combat tip, even if the speed decreases slightly.

We are only interested in uniformity in rigidity. The simplest and only way is to purchase arrows from well-known manufacturers and not bother with anything else. Moreover, for them, the “firms” always indicate both the mass and the “spine”. It is very difficult to correctly measure the spine of a short crossbow arrow at home; you can bend it or break it.

A few words about digital indexes. For example, let’s take one of the most popular and widespread arrows with the index “2219”. So, the first two numbers indicate the outer diameter of the boom in 1/64ths of an inch, and the second two indicate the thickness of the tube wall in thousandths of an inch.

As for the material. These are fiberglass, aluminum and carbon. We won’t consider the first one at all – well, to hell with it. When choosing expensive branded arrows, there is no particular difference - whether they are aluminum or carbon. Among cheap products from Southeast Asia, it is better to choose carbon. I’m not an expert in the Technology of Structural Materials, but I think that carbon in production is more technologically advanced and makes it possible to achieve better performance at lower costs.

In general, it wouldn’t hurt to have a special machine to detect the curvature of arrows and defects in tips. It costs about the same as one good assembled hunting arrow.

Finally, we move on to the arrows themselves. Let's start with the entertainment and recreation segment.

Budget crossbow arrows

As a rule, they come complete with crossbows. With very cheap models - a pair of aluminum 14-16 inches, like “AL 2219”.

For crossbows of a higher class or in the PKG configuration, the set will be a little richer: already four “luminos”, or even 20-inch carbon shells. The latter are indeed much better in terms of ballistics.

They don't last long. Crossbow shooting is very specific, and misses are guaranteed at first. As a result, the arrows lose their feathers, bend their tips, and even shoot like little arrows. The same thing happens when shooting not at special target shields, but at trees, barn walls, etc. It should be remembered that an arrow fired even from budget “blockers”, like the MK-250, or the recursive “Mongoose”, is able to pierce through a steel sheet with all that it entails.

Therefore, the best option would be to purchase at least a dozen more shells in reserve. “AL 2219” can sometimes be purchased quite freely, even in specialized “Sporting Goods” sections. You will have to look for more serious aluminum and especially carbon arrows, for example, in hunting stores. In our country, they most often go under the brand “Interloper”, or even something like “Arrow carbon 20 inches”. It is best to buy online with delivery. Here you can even select them by brand, taking into account how full your wallet is.

Fortunately, unlike crossbows, which require Russian certification, this is not provided for accessories. Moreover, arrows and creepy-looking hunting broadheads, until you combine them into a single whole, are not weapons individually and do not have any restrictions on sales or shipment (see fragment).

If you wish, you can follow the link to the full version of the document.

To be honest, I bought budget arrows and other similar accessories for near-sports shooting and recreation on such a popular resource as “Aliexpress” (pictured below). For me, especially during the season, their consumption becomes simply prohibitive - there are too many people who want to join... There they were considerably cheaper than their analogues sold in domestic stores. Well, you can easily check this yourself by going through the hunting stores in your city and surfing the Internet.

Alas, this opportunity is now lost...

ATTENTION! In 2016, Russian Customs banned the shipment of bows, crossbows and ALL components to them for individuals. Therefore, all information related to their purchase on global resources is for informational purposes only! In general, I recommend that you read the article “ On the acquisition of weapons and products structurally similar to weapons on foreign Internet resources.”

So, willy-nilly, I had to bow to domestic sellers :)). The prices, of course, are not Chinese, but generally acceptable. Especially for arrows in the budget segment.

If you are going to use them for more or less targeted shooting, do the following manipulations:

1. Roll all the arrows (leaving the fletches hanging in the air) on a tabletop or piece of glass to select the straightest ones. Carbon fiber ones, unlike cheap aluminum ones, let me remind you, are distinguished by better geometry from the very beginning.
2. Weigh the arrows and tips separately and select those that match the mass as closely as possible.
3. Check the alignment of the tip and arrow - very rarely, but the threads may be crooked. As is the plumage.
4. Leave the rejected specimens, if any, for friends and acquaintances, for whom all these “sniper” STP shifts will somehow be of no use to them during cheerful friendly shoot-outs.

However, the best option would be to purchase a machine to detect the curvature of arrows and defects in tips. It costs about the same as one good assembled hunting arrow.

I don’t recommend buying cheap hunting tips, much less going after an animal with them. Only as a last resort, as read about in the next chapter. But I recommend that you familiarize yourself with some of the materials in the “Hunting with a Bow and Crossbow” section. It's really not that simple.

Attention! If the article breaks off at this point, temporarily disable your ad blocker. Some of them manage to cut off the actual advertising screensavers along with the rest of the text. Moreover, they block the viewing of videos with stories about weapons, scenes of shooting or hunting.

   It is advisable to make a sample against which subsequent arrows can be checked. Otherwise, I caught myself thinking that the “new specimens” are more and more different each time, and in the end I could make a lot of bad arrows. Maybe this comes with experience?

   The arrow must be heavy. The speed that the projectile acquires depends on the design of the crossbow, and not on the arrow itself. Therefore, in order for an arrow to carry away maximum kinetic energy, it must be heavy.

   I have an idea to increase the penetrating power of an aluminum crossbow arrow. It may be new, but it dawned on me when I got my hands on it. If you put a metal or lead ball into a hollow arrow, the penetrating force will increase significantly! Those. after the arrow itself hits the target, the inertial force of the ball in pursuit will give an additional blow to the tip.

   The balance will be greatly disturbed, and with it the accuracy, especially if the ball is simply thrown into a hollow pipe, it will dangle both during takeoff and in flight

Delivery in the Moscow region and Moscow districts outside the Moscow Ring Road

When ordering an amount over 10,000 rubles, delivery is free, but subject to two conditions: 1) The order does not include large arrow catcher panels; 2) The choice of the transport company remains with us.

Delivery to a distance of no more than 10 km from the Moscow Ring Road - delivery cost 500 rubles.

At a distance of more than 10 km from the Moscow Ring Road, delivery is carried out by our courier or courier and postal services, depending on the dimensions of the parcel and your exact location. The cost of delivery is calculated individually with our manager or according to the price list of the selected service.

Crossbow trigger

The material for the manufacture of the trigger mechanism is sheet iron 6–7 mm thick.

The parts are mounted directly into the stock, without making a separate housing. A socket is cut out in the crossbow stock, through holes are drilled for the axles on which the trigger parts will be attached, and the mechanism is mounted

When using this design of the trigger mechanism, not a single (!) spontaneous operation was observed. The descent is smooth, comfortable, and requires no excessive effort.

Delivery to any region of Russia

When ordering an amount over 10,000 rubles, delivery is free, but subject to two conditions: 1) The order does not include large arrow catcher panels; 2) The choice of the transport company remains with us.

Delivery to any region of the Russian Federation is carried out using transport companies, as well as courier and postal services. Costs and terms are calculated depending on the chosen delivery method. For example, it is more profitable to send a large box to a large city by a transport company, but it is easier to send a light parcel by postal service. In any case, we recommend that you first consult with our manager.

Transport companies, such as Business Lines or PEC, deliver groupage cargo from a warehouse in Moscow to a warehouse in regional centers and large cities in the constituent entities of the Russian Federation. This is the most inexpensive delivery method, but requires you to pick up the package yourself at the transport company's office when it arrives there. We will deliver your order to the transport company's warehouse in Moscow free of charge. Transport companies do not send goods to small towns. The list of cities with which transport companies work can be found on the website of a particular company or checked with our manager.

Courier and postal services can deliver your parcel to almost any point in Russia right to your door, however, delivery of large goods will cost more than sending groupage cargo by a transport company.
