I recently aquired a M1876 "Cross Fire Trail" sadle ring carbine from Cimarron. I made my .45-60 cases from shortened .45-70 cases. My load was 11.4 grains of Unique, Remington 9 1/2 Magnum Rifle Primers and 20 each 405 grain Lee RNFP, and 20 each 350 grain RCBS RNFP cast Boolits. here are the results.
