I shoot 69gr Sierra Match kings, 25 grains Hogdon Varget, CCI #41 MilSpec primers, very light to no crimp.
I have been told you have to use the small base die set for .223/5.56 semi-auto. Don't know if that is true, but that is what I bought. $40 is not to much to spend to make sure I won't blow my face off. Same with CCI #41 primers, due to the AR's floating firing pin, but everyone said small rifle primers are fine. Again, I found #41's at a gun show and a LGS ordered some for me, so I bought and use them. I might test some Barnes for a yote hunting round when the regs are in for AR use.
