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.

Diagram of a Springfield Model 1855 Musket's lock mechanism. The small plate with the eagle on it is the cover for the Maynard tape system. Maynard's new system still required the musket's powder and Minié ball to be loaded conventionally into the barrel, but the tape system meant that the percussion cap no longer needed to be manually loaded onto the percussion lock's nipple.
The striker of the gun strikes the cap and fires the mixture. For larger guns an electric primer is used, the internal construction and action of which are precisely similar to the wireless tube already described; the exterior is screwed for the case. For percussion firing an ordinary percussion tube is placed in an adapter screwed into the case.
The next major leap in ignition technology was the invention of the chemical primer, or "cap", and the mechanism which used it, called the "caplock". Percussion ignition was invented by Scottish clergyman Rev. Alexander John Forsyth in 1807 but needed further refinements before it was gradually accepted in the 1820s to 1830s.
The Model 1855 also used the Maynard tape primer, which was an attempt at improving the percussion cap system that had been previously developed. Instead of using individual caps which had to be placed for every shot, the Maynard system used a tape which was automatically fed every time the hammer was cocked, similar to the way a modern child's ...
The primer was located at the base of the bullet, and the firing pin, or needle, penetrated the back of the case, went through the powder, and struck the primer to ignite it. [2] [4] [11] The acorn-shaped bullet used by the Prussians was carried in a Papier-mâché sabot which served not only to seal the bore, but also contain the primer. [12] [13]

The Model 1861 had a general effective range of 200 to 400 yards (180–370 m) but could reliably hit man-sized targets out to 500 yards (460 m) when used by marksmen, and used percussion caps which were much more reliable and weather resistant to fire (rather than the flintlocks of the 18th century; the last U.S. flintlock musket was the ...
