Interesting news in the world of firearms (if you follow that kind of stuff). True Velocity’s 6.8x51mm polymer case turns out to work quite well with legacy firearms (machine guns and SAWs), simply by switching the barrel. For those unfamiliar, the 7.62x51mm (which is the NATO dimensions) has the same length as the new 6.8mm, so they fit the chambers quite nicely. https://www.tactical-life.com/news/us-army-6-8mm-weapon-systems/
Not saying I called it, but does anyone remember the caliber used in the Militia issue rifle on Hayek? Hint, hint: 6.8mm, but longer than the 6.8SPC.
