Where did you get the brass?
... then I turned off my computer and lost the link.
If I can find it again I will post the link I have never seen a better set of tests/write up done.
You didn't missed a thing, however I have no idea how GIGGiDY manage to read "Ruger Mini14" from what I posted
There are no argument here that 6.8 SPC is better that a .223 when it comes to taking out into the bush to hunt, my comment is referring to your statement about putting a 6.8 SPC upper on your AR to give you some flexibility. As a restricted firearm .223 AR is more than enough for shooting paper target, switching a 6.8 SPC wouldn't really offer anything more other than higher cost.
