so, does all this mean that all the high pressure was all due to the "leade" of the barrel and not to any of the load data unless one takes into account the "tiny" amount of space that is taken up by the thicker case of a 5.56 military case that isnt manufactured into a 223 case? and would all this high pressure concern be easily dismissed as long as any round would fit into a factory magazine whether military or civilian because that would eliminate the concern of "leade"? only "so long" a round will fit into a magazine and function, and its pretty short.
