When shot in the chamber and barrel pressure developed from 3000-4000 kgs / cm, which is 5 - 8 times greater than shotguns. The length of the barrel hunting rifles is most commonly 54, 58, 60 to 65 cm of the barrel channel is not smooth but lumpy rotating. Furrows are formed between convex fields. Their number is 4 to 6, rarely 8. This device attaches to the rotating barrel of bullets, stable flight and greater range and accuracy.
The hunting caliber carbine is determined by the distance between two opposite fields and means in millimeters. In
On the barrel are precision-made sight and foresight. They can keep accurate shooting to 100-120 m. In many models of sight can be easily set for specific shooting distance - 50 meters, 100 meters on all hunting rifles can be installed and optical sight, which accuracy is increased significantly, even at a distance of 200-250 m. Over this distance with an optical sight accurate shot can produce only very skilled hunters. Optical sights are many different types and increases visual field. The first digit in the name of the optical sight is sequence increase, while the second is the angle of the visual field. Most widely used for hunting 4x32; 6x42; 8x56, and optics with a variable increase 3-6x42; 3-9x56 and others.
The large increase is not always a priority and is only used when shooting support. Quickly and easily the archer's eye is adapted to increase 4-6 times. Using the optical sight can be determined and the approximate and exact distance to the game. Some expensive models have electronic rangefinder eyepiece and on account of the exact distance. Usually with an optical gun sight adjusts for accurate shooting at 150 meters, which allows a good shot without adjustments between 140-180 meters. This feature depends on the size and weight of bullet used.
Bullets for hunting rifles have metal bushing capsules, powder charge and bullet. At the bottom of the cartridge is given caliber. The first digit indicates the diameter of the bullets, which corresponds to the diameter of the barrel channel and the second figure
- The length of the cartridge corresponding to the chamber of the barrel. With names such as letters K (the
Bullets for hunting carbine are many models and shapes. Even for the same caliber manufacturers offer different weight, shape and design bullets. This is done to the same carbine to be used for hunting other game species. In general, the bullets are divided into the following types:
1. Retaining their shape when hit. These are sharp tip bullets thick sheath and lead core »They are designed primarily for predators with valuable fur, which pierce and tear. Used for small caliber - 5.6 millimeters, 222, 223.
2. Deformable bullets. They vary in structure, most often exposed to lead top a round and
