45-70 Government - Marlin 1895 & Win 1886

Warning: SAAMI standard pressure for the 45-70 Government is 28,000 PSI. All of the listed loads are approximately 40,000 psi. They are not intended for use in original trapdoor single shot rifles or early Marlin Model 1895 or Winchester Model 1886 lever action firearms. Bullet selections are specific, and loads are not valid with substitutions of different bullets of the same weight. Variations in bullet length will alter net case capacity,  pressure and velocity. Primer selection is specific and primer types are not interchangeable. These are maximum loads in my firearms and may be excessive in others. All loads should be reduced by 5% as a starting point for development where cartridges have greater than 40 grains in capacity and 10% for cartridges with less than 40 grain capacity following safe handloading practices as represented in established mainstream reloading manuals. Presentation of these loads does not constitute a solicitation for their use, nor a recommendation.
