CCI (Cascade Cartridge Inc.), based in Lewiston, Idaho, manufactures rimfire ammunition, centerfire handgun ammunition, and primers for reloaders and industrial ammunition production. CCI made the first mini-mag rimfire ammunition in 1963, and in 1975 developed the Stinger, a high velocity .22 Long Rifle product.
The first step to firing a firearm of any sort is igniting the propellant. The earliest firearms were hand cannons, which were simple closed tubes.There was a small aperture, the "touchhole", drilled in the closed end of the tube, leading to the main powder charge.
0.175" (4.45 mm) diameter small pistol primers, and a thicker or stronger metal cup small rifle version for use with higher pressure loadings in weapons with heavy firing pin impact. 0.209" (5.31 mm) diameter primers for shotgun shells and modern inline muzzleloaders, using a Boxer-type primer factory-assembled inside a tapered, flanged brass cup.
Initially, CCI made centerfire primers for government use. As of March 2015, it mainly manufactures rimfire ammunition but also makes centerfire handgun ammunition, primers for reloading and industrial purposes, and shotgun shells. CCI was founded in 1951 by Dick Speer, brother of Speer Bullets founder Vernon Speer.
Percussion caps have been manufactured in various sizes to fit snugly over different sized nipples. Nipples for 4.5mm and 6mm percussion caps. The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition.

Below is a list of rimfire cartridges (RF), ordered by caliber, small to large. Rimfire ammunition is a type of metallic cartridge whose primer is located within a hollow circumferential rim protruding from the base of its casing. The most common rimfire cartridges are chambered for .17 caliber and .22 caliber. The bullet diameter for .17 ...
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 ...
Modern primers are basically improved percussion caps with shock-sensitive chemicals (e.g. lead styphnate) enclosed in a small button-shaped capsule. In the early paper cartridges , invented not long after the percussion cap, the primer was located deep inside the cartridge just behind the bullet, requiring a very thin and elongated firing pin ...
