This is Buffalo Bore's answer to modern 45-70 rifles that can handle serious pressure. The 8E20 looks like standard SAAMI-spec ammunition, but it packs considerably more power behind those rounds. You get 300 grain jacketed hollow points moving at 2300 feet per second from the muzzle, which translates to over 3500 foot-pounds of energy. That kind of velocity on a modern bullet design means controlled, radical expansion followed by deep penetration where you need it.
Buffalo Bore built this specifically for lever guns made after 1972 and modern single-shot or bolt-action rifles built on modern steel. The 300 grain JHP bullet design expands aggressively at their velocities, making it particularly effective on deer and medium to large game. Unlike heavier Buffalo Bore loads that penetrate straight through, this one strikes a balance between expansion and penetration, with users reporting quarter-sized entry wounds but fist-sized damage cavities after expansion.
You get 20 rounds per box with brass casings that are reloadable, so if you're into handloading, you've got options down the line. The ammo is loaded to substantially higher pressures than factory standard loads, which is important to know. This isn't the round for antique Trapdoor Springfields or vintage military rifles, but modern Marlin 1895 guns, Henry lever actions, Browning 1885s, Ruger falling blocks, and similar strong-action rifles handle it without issue. Just verify your rifle is on the approved list before loading up.
The 8E20 is designed for modern rifles only. It works in Marlin 1895 rifles made since 1972, Henry lever actions, modern Browning 1885s, Ruger falling block rifles, and similar strong-action firearms. Original or reproduction Trapdoor Springfield rifles cannot safely handle these pressures. Check Buffalo Bore's approved firearm list before purchasing to confirm your rifle is compatible.
Buffalo Bore 8E20 loads to magnum pressures and generates significantly more velocity and energy than factory standard 45-70 loads. While the cartridge dimensions are externally identical to SAAMI specs so it fits in any 45-70 chamber, the 8E20 delivers roughly 40 to 50 percent more power. This translates to faster impact velocities, more explosive expansion, and deeper penetration on game.
The 300 grain jacketed hollow point is built for controlled expansion on deer and medium to large game. At Buffalo Bore's velocities, it expands rapidly while retaining enough weight and momentum to penetrate deep. Users report consistent performance with quarter-sized entry wounds but significantly larger wound channels, making it effective for hunting at typical rifle distances.
Yes, the 8E20 comes loaded in brass cases that are suitable for reloading. After firing, you can reload these cases for future use if you're into handloading ammunition. Always follow proper reloading procedures and consult your reloading manual for load data.
