Match or Magnum primers for ball powder, even for something as small as a .223.

Cold CCI 200 behind 80 grains of ball, yea, you should expect a hang fire.

I'd expect CCI 250's or Winchester Magnums, either one to give you good results.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.

You cannot over estimate the unimportance of nearly everything. John Maxwell
