<p>The invention concerns ammunition and may be used for manufacturing cartridges of rifle arms and other kinds of ammunition, as well as for improving characteristics of sniper riffle barrels. The basic task of the invention is the improvement of the cartridge design by the following way: an additional covering on a bullet is made based on a film-forming organic carrier with filling substance which is based on the products of hydrate dehydration containing oxides providing improvement to accuracy of shooting; adverse conditions of weapon storage are rendered less influent on the accuracy, that indicates stabilization of barrel channel parameters and increase of weapon survivability. The application of the additional coating permits a faster process of leveling, smoothing of barrel channels and improvement of accuracy from 30 % up to 44,5 % and more. Meeting the requirements of the weapon exploitation technical specification and the maintenance instruction permits the regenerative effect to progress and to reach 60 % according to the criterion of accuracy both during the storage and the operation.</p> |
