Candidates must have at least 90 credits from an accredited college, approval from the state RTI board, and falling in the age range of 18 to 41 years. [32]
SMc cartridges were developed in an attempt to produce an efficient cartridge combining low recoil, low heat, and high velocity. [4] The 5 mm/35 SMc has produced velocities in excess of 4,800 ft/s (1,500 m/s) shooting a 30-grain (1.9 g) molybdenum disulfide-coated Berger bullet from a 28-inch (71 cm) Pac-Nor barrel, far higher than its commercial counterpart the .204 Ruger.
The 5.6×39mm, also known in the U.S. as .220 Russian, is a cartridge developed in 1961 for deer hunting in the USSR. [3] It fires a 5.6mm projectile from necked down 7.62×39mm brass.

[3] [4] Because of its similarities to the .223 Remington and 5.56 mm NATO, the .350 Legend is suitable for use in AR-15 type semiautomatic rifles. [1] [4]

The AR-15 standard cartridge is a .223 caliber, frequently using bullets in the 55 to 77 gr weight range. The 300 BLK can be found in factory-loaded ammunition from 100 to 220 gr. Although, the solid .308 bullets that are lighter than 150 gr do not have optimum ballistic coefficients (hollow-point bullets can have an optimum profile at a ...
