It’s The Ultimate Survival Cartridge (Because It Won’t Ever Be Banned)

Developed for use in the famous Model 1873 “Trapdoor” Springfield rifle, the 45-70 cartridge has managed to remain popular and in regular use for nearly 150 years. While commonly regarded as a big-game load – it has been used on African safaris to take elephants — it can serve as the ultimate survival round with a little care in loading and understanding, thus making any .45-70 firearm into a one-gun-does-it-all game-getter.

It originally was issued with a 405 grain bullet over a 70 grain black powder charge, but later versions included rounds with a lighter 55 grain powder charge for carbines, and a 500 grain bullet over 70 grains of powder. Any of these loads would be devastating on large game, and the full power loads suitable for even buffalo or large bear. These loads, developed with black powder pressures, are commonly referred to as “Trapdoor” loads, indicating their suitability for guns that cannot handle higher pressures. These include the many original and replica Springfields running around, and certain older Harrington and Richardson single shot rifles, and such.

However, stronger actions have been developed, and many modern .45-70s can take higher pressure loads made with smokeless powders — typically Marlin and Henry lever-action rifles, and .45-70 pistols. These loads are sometimes called standard or intermediate loads, and should never be shot in Trapdoors or old black powder rifles. Moving on up are loads for strong-action rifles, such as the Ruger Number 1, and the NEF Handi Rifle. When shooting these high-pressure shoulder bruisers, it is important you only shoot them in guns warranted by the manufacturer of the ammo or gun as suitable for high-pressure loads.

After the .45-70 was invented, it didn’t take long for the Army to issue so-called “forager rounds.” These are .45-70 cases loaded with a shot-filled wooden bullet and issued for hunting game, and also where we start exploring the world of the .45-70 as an all-around survival cartridge. We are probably familiar with “snake shot” or “rat shot” rounds for the .22 and some common handguns, and the same concept can be scaled up for the .45-70, and will successfully take game out to a few yards. While it’s no long-range game-getter, it is suitable for taking small game at realistic ranges. Since these sorts of shells have to be made by hand, some experimenting with powder and shot charges will be needed to find the right load for your gun. While not a substitute for a traditional small-game gun, these will work, and are the first step into creating a survival loadout for your favorite .45-70.
