Product Overview
Buffalo Bore's 350-grain JFN is a jacketed flat nose .45-70 load made for grizzly, bison and Cape buffalo. Its bullet is a lead core in a jacket with a wide flat tip in place of a point. It leaves the muzzle at 2,145 fps with 3,578 ft-lbs.
At 2,145 fps it is the fastest standard-pressure load in the caliber, and it kicks harder than every load it is compared with. A jacketed flat nose over a lead core makes this a hunting load, and the recoil shows it over a long string.
If you're cross-shopping, Underwood's +P 325-grain Xtreme Hunter starts 130 fps faster on a bullet 25 grains lighter and carries 3,736 ft-lbs at the muzzle. Barnes' VOR-TX 300-grain TSX is the copper bullet beside it, 220 fps slower with 1,109 ft-lbs less.
- The most muzzle energy of the standard-pressure .45-70 loads
- Still moving at 1,567 fps at 200 yards
- Starts 692 ft-lbs ahead of Hornady's LEVERevolution 325-grain FTX
- About 24 percent more recoil than Hornady's LEVERevolution 325-grain FTX in the same rifle
- A lead core, so it cannot be used where lead-free ammunition is required
- Only the caliber's two heaviest loads kick harder
