The .45-70 suppressor friendly rifle cartridge, also known as .45-70 Government, was developed at the U.S. Army’s Springfield Armory for use in the Springfield Model 1873.
The .45-70 has survived to the present day. The traditional 405-grain load is considered adequate for any North American big game within its range limitations, including bears, and it does not destroy edible meat on smaller animals such as deer due to the bullet’s low velocity. which also makes the .45-70 suppressor friendly. It is very good for big-game hunting in brush or heavy timber where the range is usually short. The .45-70, when loaded with the proper bullets at appropriate velocities, has been used to hunt the African “big-six”. The .45-70 suppressed has been loaded and used to hunt everything from deer to elephants.
