In 1975, CCI engineers completed development of the first "hyper-velocity" .22 Long Rifle ammunition. This ammunition became known as the "CCI Stinger." [7] In early 2020, CCI introduced 14 new products. [8] CCI/Speer sells the Gold Dot line, component bullets, and handgun ammunition using a bonded copper-plated hollow point bullet.
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.
Chemical primers, advanced metallurgy and manufacturing techniques all came together in the 19th century to create an entirely new class of firearm — the cartridge arm. Flintlock and caplock shooters had long carried their ammunition in paper cartridges , which served to hold a measured charge of powder and a bullet in one convenient package ...
The CCI stems from the original CRB Index, created in 1957. It is a ‘snapshot’ of the index at its 9th revision in 1995, before it underwent weighting and rebalance changes in the 10th revision. It is sometimes referred to as the ‘Old CRB’. The 17 components of the CCI are continuously rebalanced to maintain the equal weight of 5.88%.
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.

The reduced mercury which results forms amalgams with cartridge brass, weakening it, as well. Today, mercury fulminate has been replaced in primers by more efficient chemical substances. These are non-corrosive, less toxic, and more stable over time; they include lead azide, lead styphnate, and tetrazene derivatives.
Opened in 1816 on 20 acres (8.1 ha) of land purchased by President James Madison, it was the center of U.S. military small-arms ammunition design and development until its closure in 1977.
The CCI is a versatile indicator capable of producing a wide array of buy and sell signals. CCI can be used to identify overbought and oversold levels. A security would be deemed oversold when the CCI dips below −100 and overbought when it exceeds +100. From oversold levels, a buy signal might be given when the CCI moves back above −100.
