The .30 RAR rifle cartridge was developed to fill a perceived gap in performance on game between the .223 Remington and larger cartridges such as the .308 Winchester and the 6.8 SPC. Design of the cartridge is considered a joint effort between companies under the "Freedom Group" name through a private equity firm and included such companies as Bushmaster, DPMS and Remington itself.

| - The .30 RAR rifle cartridge was developed to fill a perceived gap in performance on game between the .223 Remington and larger cartridges such as the .308 Winchester and the 6.8 SPC.

- Performance tests between the .30 RAR and the .308 Winchester show that while the .30 RAR does have a good muzzle velocity, the energy it is capable of delivering on target at around 400 yards decreases significantly. Combined with the poorer ballistic coefficients of the lighter projectiles (.267 for the 125 grain Core-Lokt), this makes the .30 RAR a cartridge suited to ranges around 300 to 400 yards where a larger calibre projectile is required.

A side effect of the short, wide case has meant that the Remington R-15 Rifle which was designed alongside the cartridge uses a four round, single stack magazine.
