Ok, I am on a reloading kick since purchasing all the gear about a week ago. I have been successfully loading .40SW and .223 and continue to add die sets to broaden my abilities...... I own both a M-44 and a Romak-3 and would love to load some better quality ammo for these guns. I have heard that using brass-cased ammo in the Romak is verboten, something to do with the action being too violent and ripping the rim off - then loading a new cartridge into the damaged one, screwing everything up.......any truth to this? Anyway, is there a good source for reloadable brass for this caliber? Any recommended bullets/propellants?
