With all of the gov't/media induced hysteria in the USAicon this Winter, there's been a run on reloading components and projectiles as well as firearms and accessories. I doubt seriously that the projectile manufacturers will expand their product lines to include Mk.7 projectiles any time soon if at all now since they can't even produce the ones that are standard sales items now. Of course, if someone wants to pony up the cash for a 250,000 projectile order, they'll probably consider it.
