Buffalo Bore's 8B20 Lever Gun Strictly Business load steps up the .45-70 with higher pressure performance while maintaining external compatibility with standard SAAMI chambers. This is important because it means the rounds chamber in any .45-70 rifle, but only safe firearms built for elevated pressures should use them.
The 405-grain semi-jacketed flat point pushes through thick bone and heavy game like few rounds can. This weight class is the traditional heavy-for-caliber choice that has worked on North American big game for well over a century. The flat point design feeds reliably from tubular magazines while delivering the stopping power that made this cartridge legendary in lever guns.
At 2,000 fps and 3,597 ft-lbs of muzzle energy, these loads step well beyond standard factory .45-70 ammunition. They're built for rifles like the Marlin 1895 (made since 1972), Browning 1885 and 1886 models, and other strong modern actions. Do not use in older or original Trapdoor rifles or weak actions, as the higher pressure will damage them.
Whether you're zeroing in before a hunt or working up a load for the field, these 20-round boxes give you quality factory ammunition that eliminates reloading. Each round is built to Buffalo Bore's real-world velocity standards, tested from practical barrel lengths so you know what to expect from your rifle.
Buffalo Bore 8B20 is designed for strong, modern lever actions and break-open single shots. Safe firearms include Marlin 1895 rifles made since 1972, all Browning 1885 and 1886 models, Rossi Rio Grande, and New England Arms Handi Rifles. Never use in older Trapdoor rifles or weak actions, as the higher pressure can cause damage. Check the manufacturer's complete list for your specific rifle.
Yes, the 8B20 will chamber in any .45-70 rifle, but that doesn't mean it's safe for that rifle. The rounds look like standard .45-70 but generate far more internal pressure. Always verify your firearm can handle higher-pressure loads before firing Buffalo Bore ammunition.
The 405-grain semi-jacketed flat point is designed for deep penetration and terminal performance on large game. Combined with 2,000 fps velocity and nearly 3,600 ft-lbs of energy, this bullet configuration delivers consistent expansion and excellent wound channels. It's proven effective on elk, bear, and other heavy game when fired from appropriate firearms.
These rounds work for both hunting and target shooting in suitable rifles. The semi-jacketed construction and flat point deliver good accuracy and consistent performance downrange, making them practical for range work and sighting in before a hunt, though recoil is noticeably more pronounced than standard loads.
