45-70 Govt – 300 gr JSP – Federal Power-Shok (4570AS) – 200 Rounds

A 300 grain bullet at moderate speed turns the 45-70 into a flatter-shooting big game cartridge while keeping the heavy-hitting character lever gun hunters love. This listing is Federal Power-Shok 45-70 Government 300 grain jacketed soft point ammo, MPN 4570AS, sold as a 200 round case for deer, elk, bear, and hogs.

Federal rates this load at 1,850 fps with 2,280 ft-lbs of muzzle energy, considerably faster and flatter than 405 grain loads. The jacketed soft point bullet has exposed lead at the nose to start expansion, and its flat nose profile is safe for tubular magazines. The added speed extends practical range somewhat while still delivering the large, deep wound channel the 45-70 is known for. It is a hunting load designed for big, tough game at woods and brush distances.

This ammunition fits modern rifles chambered in 45-70 Government, including the Marlin 1895 and 1895 SBL, Henry All Weather and Side Gate, Ruger No. 1, Browning 1886 reproductions, and Thompson Center Encore and Contender. A common question is whether this load is safe in Trapdoor Springfields or other antique rifles. Original Trapdoors should only be fired with loads specifically described as safe for them after a gunsmith’s inspection. Another common question is whether 300 or 405 grain is better for elk. Both work at close range, and the 300 grain shoots flatter, while the 405 grain offers more weight for penetration.

Federal 4570AS is new production ammunition, not reloads, loaded in Anoka, Minnesota. Each round uses a reloadable brass case with a boxer primer and non-corrosive priming. This case ships as 10 boxes of 20 rounds for a total of 200 rounds from one lot. 45-70 brass is expensive to buy new, so keep your fired cases if you reload. A case lets you practice with full-power loads and still have plenty for several seasons of hunting.
