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 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.

Between the primer pocket and the case chamber are one or more apertures known as flash holes, which serves functionally as a touch hole inside the cartridge. In artillery, priming powder, a fuse, squib, or friction igniter is inserted into the touch hole to ensure ignition of the charge. The ignition might be achieved via striking or electrically.
It was found that the only cartridge then in service suitable for use with the new lock was the .45 ACP. General Thompson envisioned a "one-man, hand-held machine gun" chambered in .45 ACP to be used as a "trench broom" for the ongoing trench warfare of World War I. [35] Oscar V. Payne designed the new firearm along with its stick and drum ...
In the case of the .45 ACP, the new standard cartridge pressure is 21,000 psi (145 MPa) and the SAAMI .45 ACP +P standard is 23,000 psi (159 MPa). This is a common practice for updating older cartridges to match the better quality of materials and workmanship in modern firearms. [20]
