A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

This article lists firearm cartridges which have a caliber in the 2.00 to 2.99 millimetres (0.079 to 0.118 in) range. All measurements are in mm (in). 2 mm cartridges

Pellet exiting muzzle, with formula for energy overlaid.. Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge.
However, the ammo was much heavier (393 gr (25.4 g) for 7.62 x 51 round compared to 160 gr (10.4 g) for .45 ACP), effectively limiting the ammo load. Additionally, when fired in full automatic mode free recoil delivered by full-sized and full-powered cartridges became an issue, too.
The .275 No 2 Magnum's performance is comparable to the .275 Rigby. [1] As is common with cartridges for double rifles, due to the need to regulate the two barrels to the same point of aim, the .275 No 2 Magnum was offered in one loading, firing a 140 gr (9.1 g) bullet with a listed speed of 2,675 ft/s (815 m/s).

The Whisper family was developed as a line of accurate, multi-purpose cartridges using relatively heavy rifle bullets for a given caliber in subsonic loads. [1] [2] [3] The intention was to create an extremely accurate cartridge family for military, police, competition and specialized hunting markets that could also be easily sound suppressed.
Among other weapons, I had an extraordinary rifle that carried a half-pound percussion shell—this instrument of torture to the hunter was not sufficiently heavy for the weight of the projectile; it only weighed twenty pounds: thus, with a charge of ten drachms [270 grains] of powder, behind a half-pound shell, the recoil was so terrific, that ...
