Measurements of standard 7.5 cartridges loaded with 95 gr (6.2 g) bullets showed a muzzle velocity of 2,000 ft/s (610 m/s) out of a 5.3 in (13.46 cm) barrel equal to 4 in (10.16 cm) of free bore and a muzzle energy of 845 foot-pounds force (1,146 J), which is almost 50% higher than the 357 magnum 125 grain JHP when using premium quality high ...
Check out the ballistics and ammo types on the increasingly popular 5.7x28mm. See what popular firearms like FN and Ruger shoot 5.7.
Bullets weighing 2.6 g (40 grains) or less are recommended for optimal use in 5.7×28mm applications, but the 228.6 mm (1:9 in) rifling twist rate (distance the bullet must travel to complete one full revolution) used in the firearms' barrels will stabilize bullets weighing up to 4.5 g (70 grains).
If you’re interested in picking up an FN P90, you’ll want to examine the ballistics of 5.7x28 ammunition. The charts below will show you the ballistic performance of this small caliber.
Typical velocities to expect from the 25.6” barreled K31 without exceeding recommended pressures are 2900fps with 150gr bullets, 2750fps with 165 to 168gr bullets, 2600fps with 178-180gr bullets and 2400fps with 200gr bullets.
The 7.5×54mm French, 7.5 French, or 7.5 MAS (designated as the 7,5 × 54 MAS by the C.I.P.) is a rimless bottlenecked rifle cartridge. It was developed by France as an update to the 7.5×57mm MAS mod. 1924 cartridge.
The following are calculations of conventional ballistic data for the 7.5 FK® cartridge. F9: All copper monolithic wide meplat flat nose. This bullet is designed to create a wide and very deep permanent wound channel in addition to a very high dynamic shock effect.
