Actually....he IS right! Federal was making the M72 match ammo.....I was b!tching at the DCM about it (LC 77 M72) in 1988 and he admitted that Federal made it all through the 1960's and 70's.....LC made the brass and Federal had the contract to load it along with at least some of the M852/M118. At the time, LC had bigger fish to fry than small-runs of specialized competition ammo!
