I would like a 45 colt lever to accompany my Ruger Vaquero and Redhawk in 45 colt. Those will occasionally see some very stout "Ruger only" loads. Which lever actions can and can not handle "Ruger only"?
The Marlin 1894, Winchester 1894 and various 1892 replicas and reissues can handle loads heavier than "Ruger only". With the 1892's being the strongest of the bunch, up to 50,000psi.
Brian Pearce suggests that even the Uberti 1873's are good to ~20,000psi.
Standard loads only for any of the brass framed levers, like the 1860 and 1866.
