Among the calibers that came from the military is the 7×57 mm Mauser.
It’s surprising how many of our most useful and reliable cartridges started life in the military. Some that quickly come to mind are the .45 Colt, .45 ACP, .308 Win., .223 Rem., and the glorious .30-’06 Sprg. And right in among those, I also have to add another great performer, the 7×57 mm Mauser. The 7×57 mm, although less popular in this country, is an excellent performer featuring good accuracy and moderate recoil.
