.30 RAR
Encyclopedia
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.
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 .

Cartridge Performance
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 .
