Those .233 Remington and 5.56N rifles made before the Ban had TWO DIFFERENT chamber types. The older rifles designed around the .223 Remington and older M193 Ball round used a lot looser twist (1-in-10) and the NATO 5.56mm round (M855) requires a tighter (1-in-7) twist. To add to the issues, the M855/SS109 round had a "microscopically" larger case mouth (due to the higher pressures produced) that would "expand" into older rifle's bores and jam them. When you put older ammo (M193 Ball) into newer rifles, that ammo wouldn't reach the same ranges or possess the same accuracy as the newer ammo. To make sure there was less "confusion" about the difference between the two ammo types, OLDER RIFLES (designed for M193) were now being designated as .223 Remington ammo rifles while the rifles designed for M855/SS109 were designated as 5.56mm NATO rifles. Any NATO designated rifle CAN fire all .223 ammo. Just reduce the weapon's base range by 5 meters. Firing M855 in a .223 Remington chambered rifle will create a JAM if the user rolls OVER the rifle's WEAR VALUE. This roll MUST BE MADE after every Initiative Step's/Attack's worth of fire. A failure by more than two on this roll will mean a Level 2 malfunction.

The Air Force and foreign aid mean that Lake city still does a lot of the 55gr M193 ammunition. Also once a year, employees may buy up to 1 or 2 thousand rounds of M193 and M80 loose ball. When Winchester and Remington ran the plant, employees enjoyed discounts on firearms as well.
