6.5x38mm Caseless
Overview
The 6.5x38mm is a caseless munition which consists of a projectile nestled within a circular block of propellant. Unlike it's predecessor caseless ammunition, It has resolved issues with cook offs and feeding problems. The 6.5x38 is modelled heavily after the 6.5 Grendel round, albeit much lighter and available in numerous military loadings such as AP.
Prior to the collapse of the US military, the CmmG MX series chambered in 6.5x38 was in the process of mass adoption, with a vast majority of frontline units having been supplied before ultimate collapse. That paired with adoption by other small nations has led to a relatively decent supply of them globally.
