6mm Mach IV
Hey guys just picked up a new gun out of the local paper, trouble is I can't find load data on it anywhere. Closest thing I've found was that there was an Nov 1993 Guns and Ammo article on it that probably has some data in it. There is also a little info on a very similar cartridge called the .240 incinerator. Anyway, any help will be much appriciated.
