Buffalo Bore 45-70 Government 430 gr hard cast lead flat nose ammunition is a heavy-for-caliber lever-gun load intended for use in strong, modern and traditional actions. It uses brass cases and delivers substantially greater velocity and energy than standard SAAMI 45-70 loads. This cartridge is offered for target shooting and similar applications where a robust, hard-cast projectile is desired.
This loading generates significantly more power and pressure than standard SAAMI-spec 45-70 ammunition and is not safe in every 45-70 firearm. It is supplied with manufacturer guidance that limits safe use to specific strong-action platforms, including Marlin 1895 models (post-1972), Browning 1885/1886-type rifles, Rossi Rio Grande, New England Arms Handi Rifle, T/C Encore, modern falling-block actions (Ruger #1 and #3, Shiloh, Christian, Persoli Sharps), Winchester 1886 iterations made since 1915, and Siamese Mauser bolt actions.
