M1898 rifles and carbines seem to be prone to have the rim hang up on the forward shoulder of the cutoff mortice when the cutoff itself is removed. M1892 and 1896 rifles/carbines seem to feed fine with the cutoff removed. The difference is the position of the forward shoulder of the mortice. The 1898's have the "short" cutoff with matching short mortice; the older rifles have the longer cutoff and the shoulder of the mortice is further forward. By the time the rim of the cartridge gets there, it has started to enter the chamber and has pivoted away from contact with that side of the receiver.
