On the shelves of specialized stores, ready-made factory shot and bullet cartridges are presented to the attention of hunters. Judging by consumer reviews, these ammunition show good results that are not inferior to the passport characteristics of a particular shooting model. However, to achieve better performance with such cartridges is difficult, because the guns are not provided for the same barrels. Different manufacturers produce hunting rifles, the barrel channels of which, despite the same caliber, have different diameters and muzzle narrowing. Correct the situation by self-equipping hunting cartridges. For this purpose a shutter is used. What it is? What is it for? Information about what it is - an obturator in a cartridge is presented in the article.
Acquaintance
Obturator - what is it? This term is called a special mechanical device whose task is to block the flow. It may be light or some other radiation in an optical device. In this case, filming and cinema projection equipment are equipped with obturators. In optics, this mechanical device is mainly called 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 a cuff-seal, which is equipped with a wetsuit. It is designed to reduce the flow of water into the sleeves. Obturators are also found in the rocket industry. This mechanical device is equipped with launch complexes. The obturators' job is to push rockets out of the mines.
About the mechanical device for ammunition
Novice hunters also ask the question: "What is a shutter?" 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-shutters are powder and shot. Let's consider each of them.
About powder shutters
What it is? What is this mechanical device intended for? Thanks to the powder obturators, dispersion of the powder gases in the barrel channel is prevented. As a result, they have a stronger effect on the wad, which is responsible for pushing the projectile. Judging by the reviews, many hunters give preference to felt and wood fiber wads. Their improved obturation will be possible if technical petroleum jelly is used as a lubricant. Wads should have the correct cylindrical shape. In an effort to prevent adhesion of grains, wads are equipped with cardboard pads.
The wad thickness is 0.1 cm. Guns of 12 caliber 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 buy a plastic wad container with a 12-gauge seal. Judging by the numerous consumer reviews, with this product the shot is provided with good pressure, uniform scattering and increased accuracy. Cardboard pads can not be used with wad-wraps. Some hunters equip the shutter with a single fiberboard wad or pour sawdust over which a cardboard lining is laid. This provides a good shooting result at any distance.
About Shot Products
These devices are designed to hold shots in ammunition and create pressure in the barrel channel. The thickness of such wads varies from 1 to 4 mm. They are made of cardboard or plastic. 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 it completely flies.
Finally
Theoretical training is not a guarantee that the cartridge equipment will be performed correctly. When choosing a shutter, the features of hunting, the characteristics of the gun and the ammunition used should be considered.
