Negative. Wherever you read that was mis-informed and spreading fake news.
Federal XM-855 and XM-193 ammo is the same as NATO/military spec. They cannot sell "M-855" and "M-193" directly to the public due to assorted government regulations. All ammo that is produced for the military, but after testing is determined out of spec due to velocity, pressure, temperaturesensitivityissues, etc, is "demilitarized" or "demilled" by disassembling all the cartridges in that lot. Hence, why you have resellers of "pulled" or "demilled" projectiles, WC842, WC844, WC846, WC857, WC860, etc powders.
