A ball or round bullet refers to bullets for a hunting rifle that do not have stabilization in flight. In the past it was used very often, now less often. However, in remote areas where it is difficult to purchase factory-made bullets, it is popular for its ease of manufacture at home..
Ordinary and arrow-turbine type bullets for a hunting rifle, round bullet, Jakan bullet, Brenneke bullet, Witt bullet, properties and application.
Some hunters prefer to use a round bullet because of habit or local traditions. Usually round bullets are cast or rolled from pure lead. In general, round bullet shooting performance is usually worse than that of bullets of other designs, but with careful adjustment of the round caliber round bullet to medium distances, you can shoot very high quality.
The diameter of the round bullet should be such that it freely passes in the narrowest part of the channel, that is, 0.1-0.13 mm less. A caliber bullet is fired from the barrel of a cylindrical drill. In other cases, it is better to use a sub-caliber bullet. A round bullet needs to be centered, especially when shooting from a choke. To do this, use two felt wad, salted cloth or suede. Or use other devices.
It should be remembered that a round bullet can give strong bounces (sometimes multiple) from tree trunks or thick branches, from water, from frozen ground and the like, therefore it cannot be used for collective hunts.
Bullet “Sputnik”, properties and application.
The Sputnik bullet is almost the same as a round bullet, but differs by the presence of perpendicular ribs on the surface. In most countries of the world, a round bullet is now not manufactured factory. An ordinary round bullet can be not only spherical, but also cylindrical in shape. Such a round bullet did not have wide distribution, but now it is not used at all.
Bullet Yakana (Jacana), properties and application.
Bullet Yakana (Jacana) refers to bullets arrow-turbine type. It was widely distributed several decades ago, now it is quite rare. The hollow head part of a bullet, covered with a lead cone or filled with wax, has four (less often six) cuts along which it unfolds upon meeting with a target, as a result of which the bullet inflicts more serious damage to the beast.
It’s bad to shoot a Yakan bullet in a forest, in a bush, in reeds, because when it hits a branch, it deforms and loses its correct flight. It is not recommended that she shoot long distances.
Brenneke bullet, properties and application.
The Brenneke bullet is one of the most common and widely used bullets. Despite the fact that it appeared in the last century, various modifications of it are still used. The Brenneke bullet has a cylindrical shape with a protruding cone in the front and an internal cavity in the back. The bullet itself is connected with a felt-stabilizer wad with a screw or screw.
The outer surface carries 12 inclined ribs, which should provide stabilization of the bullet in flight, and an obturating belt. It gives good shooting performance (high speed, high energy). The negative qualities include unpredictable crushing of the ribs during the passage of a muzzle narrowing, which can lead to deflection of the bullet, as well as the complexity of manufacturing. When shooting in the forest, it may deviate when passing through small branches.
The Brenneke bullet was created and modified at a time when it was fired primarily with smoke powder, and was designed for relatively small (350-380 m / s) initial speeds. Now, when the vast majority of hunters use smokeless gunpowder, giving an initial flight speed of more than 450 m / s, the performance of this bullet has worsened (the same applies to the Yakan bullet), since its deformation increased at the time of the shot.
Witt bullet, properties and application.
The Witt bullet is an advanced model of the Brenneke bullet, adapted for use in combination with smokeless powder. She has 8 inclined ribs, large in height and having a cross-section in the form of a triangle. There is no obturating belt in the lower part of the bullet, but there is its own polyethylene sealer at the bottom of the felt wad, and the wad itself is much larger in height. This bullet has very good ballistic performance..
Bullets similar to the Brenneke bullet were proposed by other authors. For example, in the magazine “Hunting and hunting economy” for 1974, a Bogen bullet is described, which differs from the Brenneke bullet in size, the use of a steel core and a connecting rod, and even greater manufacturing complexity. This model, as well as a number of others, for example, Anokhin’s bullet, was not widely used.
In recent years, some types of bullets that had felting stabilizing wads in the past (Yakana-Brenneke) are produced with wads made of polyethylene. Without entering into a discussion about the correspondence of these bullets to the above-mentioned models, it is possible, despite the lack of material, to assume that their ballistic characteristics have not fundamentally changed in comparison with the original bullets.
