The Sellier & Bellot 45-70 Government ammo in 405-grain jacketed soft point configuration is built for lever-action rifles and single-shot platforms where chamber pressures stay within SAAMI specs and terminal performance on target depends on predictable bullet expansion. This load exits a 24-inch test barrel at 1509 feet per second, generating 2044 foot-pounds of muzzle energy — enough to anchor medium game at typical woods ranges while maintaining accuracy through iron sights or low-power optics. The exposed lead nose of the JSP bullet initiates expansion on impact, creating a controlled mushroom that transfers energy into tissue without excessive fragmentation. Sellier & Bellot has manufactured cartridge ammunition since 1825, and since 2009 has operated under the CBC/Magtech family alongside MEN, positioning the company among the largest ammunition producers globally. Each round uses a non-corrosive boxer primer seated in new brass cases, making spent hulls suitable for handloading after inspection and resizing.
Built for the Box
The 405-grain projectile carries a G1 ballistic coefficient of 0.32 and a G7 BC of 0.16, reflecting the blunt nose profile typical of lever-gun ammunition designed to feed through tubular magazines where pointed bullets pose a safety risk. Velocity rating is supersonic at the muzzle, though energy retention past 200 yards drops off due to the large frontal area and modest BC. Case construction is brass with a boxer primer pocket, allowing for straightforward decapping and repriming if you reload. Lead content in the projectile core means this ammunition falls under California Proposition 65 disclosure requirements. The 20-round box keeps packaging compact for field carry or range bags.
