Big difference in match ammo and M80 ball if that's the comparison you are making. Tolerances are held much tighter on the match stuff hence the price difference. Last batch of Federal M80 I bought is pretty sloppy, occasionally get a 1 MOA five round group but see plenty in the 3 MOA range, still great for banging steel at 100 yards. I have some FN M80 ball that shoots 1 MOA easy all the time. FGMM is the most consistent I have used but that Prvi Wash suggested is right on the heels of the FGMM, any difference could very well be my imagination.
