Some time ago, Jan Libourel wrote in a "home defense" article that he had found lever action rifles chambered for pistol calibers (.357, .44 mag, 45 Colt, etc) to be unreliable in terms of feeding. He speculated that could have been due to the straight wall design of the cartridges as distinguished from the bottle neck cartridges most of the levers were first designed for. I have not seen these comments elsewhere, but for obvious reasons, this is an important issue given the increasing number of those carbines being sold, and used. Is this just an example of a gunwriter's baseless blathering, unsubstantiated by any evidence, or are there objective data that support his belief?
