cartridge under their own name. A-Square's submission was called the 6.5-08 A-Square. Some users continue to refer to the cartridge under this name. Since the acceptance of the submission by Remington Arms for the standardization of the 6.5-08 cartridge by SAAMI, A-Square has dropped the cartridge from their line of cartridges chambered for their rifles and no longer offers ammunition in this cartridge. Instead A-Square LLC has gone on to produce rifles and ammunition for the 6.5-06 A-Square cartridge which is based on the .30-06 Springfield necked down to .264 caliber (6.5 mm). This cartridge provides over a velocity advantage over the .260 Remington.
