@Alexwalker: I was proficient with the M16 rifle (4th award expert), service shotguns (plenty of range time and practical use), the M9 (3rd award expert), the M249 (carried as a primary for a while and used the fuck u of it at ranges and in combat), the M240 (same), the M2 (same), the Mk19 (same), the M224 (trained to serve as a provisional operator), and the M203 (range time, qualification, and combat use). Nothing I used fired a proprietary round, nor an ill-defined one, so no, nothing that was by the technical definition a "wildcat," but our DM was issued match-grade ammo for his SAMR, and the dude somehow got some more lethal shit sent to him from the States.
