Not all rumor - the later .357s/.44s could be pretty bad on the inside. It took me several complete tear downs and finish fitting and polishing to get my Trapper to cycle SATISFACTORILY. It would still jam and experience the infamous 'under lever cartridge drop' which was a real PITA. After a few years of watching the evolution of the new Henry and handling a few I decided my Winchester collection would be reduced to the traditional calibers and my .357 lever was going to be a Henry!
