Before getting a quantity of the exposed lead tip ammo, buy a box and ensure it feeds reliably. The M1 Carbine series feed directly from the magazine,nose-first onto a feed ramp, which subsequently re-directs the cartridge into the chamber. Often exposed lead bullets will deform and cause jams upon impact with the feedramp. My experience indicates the greater the amount of lead exposed, the greater the probability of jams.
