Primer-actuated cartridges/piston primer cartridges use a primer in the form of a blank to contain the propellant within the cartridge, or as a piston to unlock the bolt and cycle the weapon's operation. Examples are the 9×51mm SMAW, MBA Javette and the M48A2.
Small arms ammunition pressure testing is used to establish standards for maximum average peak pressures of chamberings, as well as determining the safety of particular loads for the purposes of new load development. In metallic cartridges, peak pressure can vary based on propellant used, primers used, charge weight, projectile type, projectile ...
The 6.5×47mm Lapua has a base diameter and overall length similar to the 7.62×51mm NATO/.308 Winchester, allowing it to accept the same bolt heads and fit into similar short actions and magazines. A small rifle primer that is easier to seat and allows for higher case pressure than a large rifle primer.

Components of a modern bottleneck rifle cartridge. Top-to-bottom: Copper-jacketed bullet, smokeless powder granules, rimless brass case, Boxer primer.. 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 ...
With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers. For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...
A small rifle primer .308 Winchester case is first cut down then resized to .45 ACP specifications, then primed with a small rifle primer as opposed to using the lower pressure pistol primer. Using the higher pressure small rifle primer with .308 Winchester brass designed to withstand higher pressure rifle charges gives this .45 ACP wildcat a ...
The primers for the cartridges were non-corrosive because the M1 carbine's gas-system would have fouled or corroded if standard corrosive primers were used. It only came in Grade R ("Rifle") because the M1 Carbine was semi-automatic only, dispensing with the use for Grade 2 for an automatic weapon.
