On the shelves of specialized stores, hunters are presented with ready-made factory shot and bullet cartridges. Judging by the feedback from consumers, these ammunition show good results, which are not inferior to the passport characteristics of a particular rifle model. However, it is difficult to achieve the best performance with such cartridges, since the same barrels are not provided for the guns. Different manufacturers produce hunting rifles, the barrel channels of which, despite the same caliber, have different diameters and choke points. You can correct the situation by self-equipping hunting cartridges. For this purpose, an obturator is used. What it is? What is it for? Information about what it is - an obturator in a cartridge, is presented in the article.
Introduction
Obturator - what is it? This term refers to a special mechanical device, the taskwhich - to block the flow. It can be light or some other radiation in an optical device. In this case, filming and film projection equipment are equipped with obturators. In optics, this mechanical device is preferably referred to as a photographic shutter. In medicine, obturators are presented in the form of prostheses and special devices with which they close or clog unnatural openings in the wall of the oral cavity. In diving, the obturator is the sealing cuff that comes with the wetsuit. It is designed to reduce the flow of water into the sleeves. Obturators are also found in the rocket industry. Launch complexes are equipped with this mechanical device. The task of obturators is to ensure the expulsion of missiles from the mines.
About Mechanical Ammo Device
Beginning hunters also ask the question: "What is this - an obturator?" This interest is due to the fact that homemade hunting cartridges are often equipped with this device. In weapons, thanks to obturators, powder gases do not pass through the gap between the barrel channel and the bullet belt. Judging by the numerous reviews of the owners, such ammunition never fails. Wads-obturators are powder and shot. Let's take a look at each one.
About powder seals
What is this? What is this mechanical device for? Thanks to the powder obturators, the dispersion of powder gases in the barrel channel is prevented. As a result, they are strongeraffect the wad, which is responsible for pushing the projectile. Judging by the reviews, many hunters prefer felt and wood-fiber wads. Their improved obturation will be possible if technical vaseline is used as a lubricant. The wads must have a regular cylindrical shape. In an effort to prevent the pellets from sticking, the wads are equipped with cardboard spacers.
The thickness of the wad is 0.1 cm. 12 gauge shotguns are very popular among hunters. The shot will turn out normal if the ammunition is equipped with so many wads, the total height of which will not exceed 0.25 cm. In a specialized store, you can purchase a plastic wad container with a 12-caliber shutter. Judging by the numerous consumer reviews, with this product the shot is provided with good pressure, uniform scree and increased accuracy. With obturator wads, cardboard spacers can not be used. Some hunters equip the obturator with a single wood-fiber wad or sprinkle with sawdust, on top of which a cardboard pad is laid. This ensures a good shooting result at any distance.
About shot products
These devices are designed to hold the shot in the ammunition and create pressure in the barrel bore. The thickness of such wads varies from 1 to 4 mm. They are made from cardboard or plastic. Home craftsmen use corks for this purpose. According to the masters, the cork is the most ideal option, since it does not need to be additionally fixed, and after the shot itshatters completely.
In closing
Theoretical training is not a guarantee that the cartridge will be loaded correctly. When choosing a shutter, you should take into account the characteristics of hunting, the characteristics of the gun and the ammunition used.
