Nope. 55 gr FMJ Remington UMC. 45 gr Winchester HP. I was also shooting some reloads with CCI 400 primers. I switched to 45 mag and it is still cratering, but it is not piercing anymore.

I was doing a little reading earlier as I'm new to reloading (kinda relevant here), on reloads the recommended primer I have seen in some cases is a Magnum version due to the high pressure of the 223. The cup is thicker. I have the Axis 223 also, and have cratered rounds I can safely say are well under max with no throat issues raising pressures. The primers which cratered were Winchester SR. I have "acquired" a few replacements in the form of CCI 450 Magnum small rifle primers (is this what you were referring to above?) hoping to alleviate the problem, we'll see... Good Luck!
