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 ...

Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components (metallic/polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded ...
Since the .44 Magnum was designed from the start as a revolver cartridge, there are no such issues, and SAAMI-compliant ammunition fires from any handguns or rifles chambered for the .44 Magnum.

The Daisy V/L rifle uses a .22 caliber (5.5 mm) low-powered external-propellant caseless round with no primer. The rifle was basically a spring-piston air rifle, but when used with the V/L ammunition the energy from the compression of the piston heated the air behind the caseless cartridge enough to ignite the propellant, and this generated the ...
The cartridge was originally sold as .44 Winchester. When the Union Metallic Cartridge Co. (UMC) began selling their own version of the cartridge, it adopted the name .44-40 (shorthand for .44 caliber and the standard load at the time of 40-grain (2.6 g) of black powder), as it
