If you consider the Marlin Camp Carbine or the Ruger whateveritis in .40 *&* to be rifles, then the .30 Carbine is also a "rifle."
I say not. It is the equivalent of a pistol-caliber carbine, on the upper end of that power scale, but way low on the "rifle" and "carbine" power scales, even restricting the inquiry to the intermediate power cartridges.
Most are reasonably accurate and shoot quite well to 100 yards. At 200 yards, the wind blows that light, blunt bullet about a LOT. At 300 yards, your're fighting trajectory and range estimation as well as the wind.
But, they are very fun tin can guns. Some people have reportedly hunted deer with them, but that's strictly a 100-yard proposition. It's only equivalent to .357 Magnum power.
