Buffalo Bore Ammunition 8B20 “Lever Gun Strictly Business” is a high-energy .45-70 Government load designed for robust lever-action and single-shot platforms and intended primarily for target shooting. It fires a 405 grain semi-jacketed flat point and produces elevated velocities and energies compared with standard SAAMI-spec .45-70 loads. Because it generates far more power and pressure than typical commercial .45-70 ammunition, its use should be limited to the specific strong actions identified by the manufacturer: all Marlin 1895 iterations made since 1972, all Browning 1885 and 1886 copies, Rossi Rio Grande, New England Arms Handi Rifle, T/C Encore, all modern-steel falling-block actions such as Ruger #1 and #3, Shiloh, Christian and Persoli Sharps, all Winchester 1886 iterations made since 1915, and Siamese Mauser bolt actions.
Box: Sold per box of 20 rounds (the standard retail unit).
Case: Case quantity consists of 12 boxes; a case is achieved by ordering the required number of boxes.
