Description
The Federal 45-70 300gr HammerDown BSP load is built for shooters who want more from their 45-70 Govt than typical factory ammunition delivers. Federal loads a 300 grain bonded soft point to a rated 1850 feet per second, producing about 2280 foot-pounds of energy. Federal HammerDown ammunition is engineered specifically for lever-action rifles. Its bullet is profiled to feed smoothly from tubular magazines and through lever actions, and its bonded core is tuned for the velocities lever guns produce, so it expands reliably and holds together for deep penetration.

Buying ammunition by the box from the same production lot keeps velocity and point of impact consistent from one range trip to the next. Keep a record of the load you carry, check your ammunition for dents or loose bullets from time to time, and rotate your carry rounds so the ones in your firearm stay fresh. These simple habits help you get the full performance Federal builds into every cartridge.
Before you trust any new load, fire enough rounds through your firearm to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Full-power loads produce more recoil and muzzle blast than typical range ammo, so practice with the Federal 45-70 300gr HammerDown BSP until you are comfortable with it, and store the rest in a cool, dry place in the original box.
About the 45-70 Government
Adopted by the U.S. Army in 1873, the 45-70 Government is one of the oldest centerfire rifle cartridges still in wide production. It fires heavy, large-diameter bullets that hit hard and penetrate deeply, making it a favorite for deer, black bear, hogs and elk at woods ranges. Modern lever-action rifles from Marlin, Henry and others keep the 45-70 popular with hunters who want big-bore authority in a fast-handling rifle.
