 As noted earlier, Remington developed two .244 loads, one using the heavier 90 grain bullet specifically designed, marketed and intended for medium-sized big game such as deer and antelope.As Remington saw the 90 grain bullet to be well suited for big game hunting they elected to match the slowest twist to that length of bullet specifically and avoid excessive projectile spin in favor of velocity.A 1 in 12-inch twist was selected and used initially.
