The head of a brass case can be work-hardened to withstand the high pressures, and allow for manipulation via extraction and ejection without rupturing. The neck and body portion of a brass case is easily annealed to make the case ductile enough to allow reshaping so that it can be handloaded many times, and fire forming can help accurize the ...
Gas checks are most commonly found in the form of a thin cup or disc made of a ductile metal. Copper, zinc, aluminum, and alloys such as brass have been used. A bullet designed to accept a gas check has a rebated base shank which permits attachment of the check without altering the maximum diameter of the bullet.
The cartridge is of a new design and was constructed to outperform popular hunting cartridges like the .30-06 Springfield and 7.92×57mm Mauser.When compared with the .30-06 Springfield the .30 R Blaser features an equal maximum chamber pressure of 405 MPa (58,740 psi) piezo pressure - which is fairly high for a rimmed rifle cartridge - but more cartridge case capacity, allowing the use of ...
The expensive individual brass cases can be reused after replacing the primer, gunpowder and projectile. Handloading reuse is an advantage for rifles using obsolete or hard-to-find centerfire cartridges such as the 6.5×54mm Mannlicher–Schönauer, or larger calibers such as the .458 Lott, for which ammunition can be expensive.

A brass catcher (also brass trap) is a device designed to capture cartridge casings, often made of brass, as they are ejected from a firearm. Various designs exist, utilizing a bag, pouch, net, or box to catch the casings. Some brass catchers, whether universal or designed for a specific gun, can be attached directly to the firearm.
The media attention gathered by the 38/44 and its ammunition eventually led Smith & Wesson to develop a completely new cartridge with a longer case length, in 1934. This was the .357 Magnum. During World War II , some U.S. aircrew (primarily Navy and Marine Corps) were issued .38 Special S&W Victory revolvers as sidearms for use in the event of ...
Although the .378 Weatherby Magnum case was inspired by the .416 Rigby case, it is considered a unique case which has gone on to serve as the parent cartridge of several high performance cartridges. The .460 Weatherby Magnum requires a case with the large propellant capacity necessary to propel a 500 gr (32 g) bullet at 2,700 ft/s (820 m/s).
