Comparison Hatsan MOD 70 vs Baikal MP-512

The muzzle velocity provided by the rifle - that is, the speed of the bullet as it exits the barrel.

All other things being equal, a higher bullet speed provides greater range and accuracy, and also simplifies aiming at long distances: the bullet flies along a smoother trajectory and requires fewer adjustments in height, and the influence of side winds decreases with increasing speed. On the other hand, this indicator directly affects the price of the rifle; and in some countries, legal restrictions on the ownership of pneumatic weapons are also related to the muzzle velocity of the bullet.

As for specific values, in the weakest modern rifles the initial speed does not exceed 150 m/s, and in the most powerful it can be 300 - 350 m/s or even more(remember, the speed of sound is 330 m/s). In general, for recreational shooting at short distances, this parameter is not particularly important, and detailed recommendations for choosing pneumatics for more specific situations can be found in special sources. Let us only note that in AEG electric drives (see “Type”) the initial speed extremely rarely exceeds 150 m/s, but this is done solely for safety reasons: such “weapons” are intended for military-tactical games and initially involve shooting at people, and the high speed would be unsafe for players even with protective equipment.

It is also wor...th considering that this indicator is not strictly defined. In any type of pneumatic it depends on the weight of the bullet (the lighter the faster); therefore, in the characteristics it is usually customary to indicate a certain average velocity for standard ammunition (usually weighing 0.5 g, in AEG - 0.2 g). In addition, in multi-compression rifles the actual speed of the bullet is determined by the degree of inflation, in gas-cylinder rifles it is determined by the ambient temperature, and in PCP models it is possible to achieve higher speeds than declared by replacing the air with a special gas (for example, helium). Nevertheless, this characteristic makes it possible to evaluate the capabilities of the rifle and compare it with other models, including those that differ in type.

The muzzle energy provided by the rifle.

Muzzle energy is the kinetic energy of the bullet at the exit from the barrel. This energy, in turn, depends on two factors: the mass and the muzzle velocity of the bullet. Thus, this indicator directly describes the overall power of the rifle: higher muzzle energy allows you to effectively fire at longer distances and/or heavier ammunition. On the other hand, an increase in power accordingly affects the cost of weapons.

Note that muzzle energy can be grounds for legal restrictions on the purchase/use of pneumatics. So, in some countries in the post-Soviet space, the maximum value allowed for freely sold rifles is 7.5 J — a special permit will be required to purchase more powerful weapons. And most freely sold rifles in such regions have a power of the order of 3 – 5 J. Such legal restrictions should be clarified separately. Lower rates are found mainly among “soft” pneumatics for airsoft (airsoft), using 6 mm plastic balls. For such models, a value of more than 2 J is already considered very solid, and in games such rifles are used with a minimum distance limit — for example, 15 m or 20 m (so that a shot from too close a distance does not injure the player).

It is also worth saying that the claimed characteristics of air rifles may, at first glance, not correspond to physical calculations. For example, for a model for the same 7.5 J..., the initial speed of 250 m/s can be claimed in the characteristics; for a 4.5 mm bullet weighing 0.5 g (the average, most popular weight), this would correspond to an energy of as much as 15.6 J. However, there are no inconsistencies here: such characteristics mean that the muzzle velocity was measured for a lighter bullet (for example, 0 .2 g), which accelerates more strongly at the outlet of the barrel. Accordingly, with heavier ammunition, the speed will be lower; it can be determined using special formulas or online calculators.

— Tree. A classic material used in firearms and then pneumatic weapons since ancient times (in fact, since its inception). Wooden stocks are strong enough on their own, and in modern rifles they are also amenable to special treatment to protect against dampness, temperature changes, etc .; while the rifles have a nice appearance in a classic style. At the same time, the wood is prone to abrasion, scratches easily appear on it, and there is a possibility of cracks. When used in simple conditions, such as periodic "shooting" in the country, this does not matter, however, for example, a wooden stock is not suitable for hunting — at least because it will quickly lose its "presentation". At the same time, this material is also somewhat more expensive and more difficult to process than plastic that is more resistant to “troubles”. Therefore, today the tree is used mainly in pneumatics of the middle and upper price range and is designed for those who are primarily interested in the aesthetics of weapons.

— Plastic. One of the most popular materials for the manufacture of modern pneumatics. Such stocks are easy to manufacture and inexpensive, while the plastic can be given a rather complex shape without any problems, which, in particular, facilitates the installation of various adjustment systems (see “Cheek Adjustment”, “Butt / Stock Adjustment”). However, its main advantage is practicality: this materia...l is resistant to impacts, cracks and scratches, comparable in strength to wood (or even superior) and has a small weight. As a result, plastic has become widespread in almost all price ranges.

— Aluminium. A fairly advanced material that combines low weight and high strength. On the other hand, aluminium stocks for classic pneumatics are generally expensive, and therefore are used mainly in high-end professional models (although there are exceptions). But in airsoft rifles that copy real weapons, the situation is somewhat different: there aluminium can be used as a simpler and more affordable alternative to steel (from which gunshot prototypes are made).
