The M07 made use of the 8x18.5 Roth M7 cartridge. The cartridge was wholly unique to the M07 and never used in any other weapons platform. The M07 frame held a built-in magazine in her pistol grip to which the operator loaded a 10-round "charger" through the open action. As such, the M07 could hold up to ten 8mm cartridges ready to fire but made for a complicated reloading process. Considering the operator would most likely be on horseback, this compounded problems somewhat.
The Model 07 made use of a rotating barrel during its firing action. The bolt surrounded the entire length of the barrel. The bolt and barrel moved rearwards when the weapon was fired. In this time, the barrel was rotated some 90 degrees and stopped so the bolt could recoil. The same process saw the spent shell casing ejected from the firing chamber and a new cartridge introduced. The barrel was then rotated and locked the breech, returning the bolt and barrel to their original firing positions, ready for the next firing action. The operation of the bolt - requested by Austro-Hungarian cavalry units - could be either by hand or through the weapon's natural firing action - half-cocking the firing pin. The gun was then ready to fire through a simply squeeze of the trigger as normal. This prevented the weapon from discharging prematurely or on accident.
