NONE of the weapons you are mentioning are designed for use with heavy bullets. not one. some may work and if you hand load you might be able to create a load thatwill work, but why?
My understanding was that the adjustable gas system on the SAFN and FN-FAL was specifically designed to cope with bullets of varying weights. In the case of the SAFN, it can be adusted to cope with grenades in single-shot mode. What else is the purpose of this system?
