Re: Frankford Arsenal 7.62/m80
M80 is standard ball ammo, i.e. it's what's issued to the Infantry troops for their M14's. Accurate enough for fire and maneuver warfare, it was never intended as match ammo. It's roughly the equivalent of Fed American Eagle, Rem/UMC, or Winchester white box in their 150gr loadings. Aside from the primer crimp it's basic goesbang/zombie ammo. Once the primer crimp is removed, do some basic case prep, and it's good (enough) brass. I have built match ammo from basic ball ammo brass, and as long as it's prep'ed OK, it's good ammo.
