12mm Jaeger Munition

== Overview ==
The 12mm Jaeger Munition is a now-retired caliber that was developed in the early Y2750's by Brownstark Firearms, Co. primarily as a high-caliber big game hunting round. Its impressive stopping power and terminal ballistics made a fitting choice for apex game such as Yodelorgs and Crested Titanhogs. Despite its power, its heavy weight and poor ability to cross over into an automatic platform resulted in its limited use for military applications. Today it is all but forgotten, in favor of more practical munitions such as 10 x 56mm IOD.
=== History ===
In the early Y2670's, the Thulian military adopted the Daxite-charged 8mm Jagter cartridge (72J8S). The Y2674 version of that cartridge used a Grade 2 Eladium alloy flathead projectile. Around Y2681, the TDO(Thulian Department of Ordinance) started developing an experimental higher pressure 12mm cartridge for a Marion-style action with a box magazine. That led to the 81JM12R service round that used a larger round-nose bullet than the 8mm Jagter while still maintaining similar velocity and terminal ballistics. 
As war technologies continued to evolve through the late Y2000's Many provincial militaries were adopting lighter-weight, higher velocity service rounds that were purpose-built for their rifles. The importance of penetration outstripped the importance of stopping power, and rounds like 12mm Jaeger fell out of favor.
