This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).
The .243 produces a velocity of 3,200 feet (980 m) per second from factory-loaded expanding monolithic copper projectiles weighing 85 grains (5.5 g) fired from a 24-inch (610 mm) barrel. [28] Other variations of commercially loaded .243 ammunition are available with bullet weights ranging from 55 grains (3.6 g) up to 115 grains (6.8 g).

The 6mm BR Remington cartridge is a .308×1.5" Barnes cartridge necked down to accommodate .243 bullets. The .308×1.5" Barnes cartridge is based on the .308 Winchester case shortened to 1.5 inches (38 mm). It is one of the earlier cartridges to follow the short, fat design concept.
While favoured by some varmint hunters, the .240 Wby. Mag. is not much liked by some reloaders because the case cannot be formed out of any other brass; one either has to buy Weatherby ammunition or reload used Weatherby cases which tend to be more expensive than those for more common cartridges. With heavier bullets the .240 Wby. Mag. makes ...
