I don't want to try and confuse you, but I received load data from a rep at Sierra for .223 and 5.56 NATO. It was interesting to see that the same bullet, weight and all had two completely different starting points. For example the .223 started at 23 and maxed at 25, then for the 5.56 the starting load was at or just below the max of the .223. Those are not the exact numbers but close, I did that from memory. I just don't feel like turning on my other computer where all my load data is.

Oh yeah, the reason for that is because you need higher pressure to cycle the AR's. too low of a pressure will slowly damage your rifle, so I hear. <----don't take my word on that
