| | | | Hugo Borchardt: Encyclopedia II - Recoil operation - How they work When a projectile is accelerated down the barrel of a firearm, all or a portion of the firearm will begin to move in the opposite direction, as required for conservation of momentum, according to the formula:
:Bullet mass * bullet velocity = recoiling mass * recoil velocity
In non-recoil-operated firearms, it is generally the entire firearm that recoils. In recoil-operated firearms, however, only a portion of the firearm is allowed to recoil, while inertia holds another portion motionless relative to the recoiling mass. T ...

| | | | Hugo Borchardt: Encyclopedia II - Luger pistol - Service The Swiss Army evaluated the Parabellum pistol and after a change to the more potent Parabellum or 7.65×23 mm cartridge (.30 Luger in USA), it was adapted in 1900 as its military sidearm, and designated as the Ordonnanzpistole 00 or OP00.
In 1900 the US purchased 1000 Lugers (in 7.65) for field trials, on the heels of a Late 1890s/1900 competition that included the Colt M1900, Steyr Mannlicher M1894, and an entry from Mauser. Later, a small number were sampled in the then brand new, more powerfull 9 mm round. Field expe ...

| | | | Hugo Borchardt: Encyclopedia II - Recoil operation - Long recoil operation Long recoil operations are found primariy in shotguns, particularly ones based on John M. Browning's Auto-5 action. In a long recoil action, the barrel and bolt recoil all the way back as a unit. Once its rearward movement is absorbed by its recoil spring, the barrel is forced forward by the spring, where it unlocks from the bolt and returns to battery. The bolt, after compressing its own recoil spring, is held in the rearmost position until the barrel returns to battery. At this point, the fired shell has been extracted and ejected, and a n ...
