Jimro,

I have a 5.56 chamber. The gun is a DPMS Heavy 20" barrel AR. It is my coyote rifle.

2ndTimer,

I noticed the pressure in the Lyman manual also. I looked up the SAMMI spec for the .223 Rem at work today and I think it was around 58,500 PSI, so 5R's QL prediction is a bit surprising. Then again, the CCI450 may make the differance. Hopefully the Chrony will tell the story.
