Buffalo Bore offers 45-70 ammunition that is externally identical to SAAMI spec 45-70 ammo, but internally it generates far more power and pressure. So, their 45-70 ammo will fit into any 45-70 firearm, but is not safe in every 45-70 firearm. Its use should be limited to the following firearms: All Marlin 1895 (1895 Marlins are all model 336 actions, chambered in 45-70) iterations made since 1972, all Browning 1885 and 1886 copies, Rossi Rio Grande, New England Arms Handi Rifle, T/C Encore, ALL falling block actions made of modern steel such as Ruger #1 and #3, Shiloh, Christian and Persoli Sharps, all Winchester 1886 iterations made since 1915 and all Siamese Mauser bolt actions.
