45-70 Govt – 405 gr Core-Lokt SP – Remington (29473 / R4570G) – 200 Rounds

A heavy, slow 45-70 bullet is one of the most dependable ways to stop big animals in thick cover, and Remington’s 405 grain Core-Lokt follows that tradition. This listing is Remington Core-Lokt 45-70 Government 405 grain soft point ammo, MPN 29473, sold as a 200 round case for hunters of deer, elk, moose, bear, and hogs.

Remington rates this load at 1,330 fps with 1,591 ft-lbs of muzzle energy. The 405 grain bullet is the classic 45-70 weight, and at this moderate velocity it penetrates deeply while expanding in a controlled way. Core-Lokt construction locks the jacket to the lead core for weight retention. The trajectory is curved compared with modern rifle cartridges, so this load shines inside about 150 yards. It is a hunting load built for big, tough game.

This ammunition fits rifles chambered in 45-70 Government, including the Marlin 1895, Henry All Weather and Side Gate, Winchester 1886 reproductions, Ruger No. 1, and single-shot rifles like the Thompson Center Encore. A common question is whether this load is safe in a Trapdoor Springfield. Remington’s moderate 405 grain load is commonly used in modern 45-70 rifles, but antique Trapdoors should be inspected by a gunsmith and fed only loads approved for them. Another common question is whether 45-70 is enough for grizzly or moose. Yes. With good shot placement, it has a long track record on large game.

Remington 29473 is new production ammunition, not reloads, made in the USA. 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. That covers sighting in, practice, and many seasons of hunting with a 45-70 on one zero. Practice at the distances you expect to hunt, since the heavy bullet’s drop becomes significant past 150 yards.
