Just soliciting experiences from others using a N4 and 55 gr. fodder (relatively inexpensive and widely available) ammo combination that does better than the Prvi M193.
Federal XM193 (at 2004 prices) would fit the bill.
If you’re set on 55 grain FMJ ammunition, you'll be hard pressed to find a better load than Hornady's. The muzzle velocity of Hornady's load was 3088 fps from a 20" Colt barrel with a standard deviation of 21 fps. The pressure curve of this load cycles common barrel lengths and gas systems well.

It's currently loaded in new Winchester brass and charged with a short-cut extruded powder that tends to burn cleaner than typical ball powders. The words 55 grain FMJ and accuracy shouldn't be used in the same sentence, but the Hornady 55 grain FMJ bullet is the most consistently accurate bullet in that category that I have tested.
All that is necessary for trolls to flourish, is for good men to do nothing.
