For hunters in straight-wall cartridge zones, 45-70 Government ammo delivers the stopping power and proven terminal performance that whitetail country demands. Nosler loads the Whitetail Country line with the proprietary Straight-Wall bullet — a 300-grain jacketed soft point engineered to expand reliably at the slower impact velocities and extended ranges where conventional projectiles fail to open. Muzzle velocity sits at 1950 feet per second with 2533 foot-pounds of energy, giving you authoritative performance from lever guns, single-shots, and modern straight-wall rifles alike.
Load Profile
The Straight-Wall bullet uses a thin jacket mouth and exposed lead nose to initiate expansion at impact velocities as low as 1400 fps — a threshold that common cup-and-core hunting bullets rarely meet. The truncated nose profile feeds smoothly in tubular magazines and break-action chambers, while the flat base and 0.191 G1 ballistic coefficient keep the trajectory predictable inside 200 yards. Nosler seats each round in new-production brass with non-corrosive Boxer primers, making spent cases ready for your reloading bench. Every component is manufactured in the United States.
