I've had one for years.
* Don't try lead bullets, even at the same weight. Fouls gas port.
* Don't try .44 Specials. The feed mechanism won't feed the shorter length.
* Don't try .44 Magnum WNFP. The feed mechanism likes SAAMI length cartridges with a rounded bullet profile. JHP's or JSP's are OK.
* Don't try downloading .44 Magnum. The gas mechanism is designed for "full-up" loads and they action won't work reliably, or at all.
Other than that, it's a nice, light carbine.
But the limitations make me like my Marlin 1894 better.
