As powder technology improved, militaries realized they could standardize on one rifle type with a shorter barrel length for all troops, without having performance suffer. In the late 19th century, many armies issued rifles, short rifles, and carbines, with the latter two types going to cavalry, engineer, and artillery troops who (it was thought) wouldn't need the range of an infantryman, and whose duties meant that a cumbersome long rifle would just get in the way. The M1893 rifle had been developed before the advent of Spitzer bullets, and like most rifles of its day it had a very long (29”!) barrel to take full advantage of early smokeless propellants to generate maximum velocity and therefore range. At the beginning of the 20th century it was still formidable if not cutting edge. It was smooth and fast, and worked great with moderately powerful cartridges. Its action is pure M1893, which to refresh your memory, is a 'small ring' Mauser design that cocks on closing (which I prefer to the later, stronger 98 action which cocked on opening). Originally chambered in the hot-for-its-day 7x57mm Mauser cartridge, the M1893 wasn't the strongest bolt action on the block, but it didn't really need to be. I've blogged about two Spanish Mausers before: the very important M1893, and the interesting FR-8. Think of the M1916 as the M1893's little brother, so to speak.
