I agree! I was only adding to your previous post with some "observations" that I've learned in researching the subject.Thoese chamber pressures are not apples to apples, they are measured by different standards. the realistic end results are comparatively similar. Any .223 chamber can easily be made to handle the range of pressures. Another thing on chamberings, there is little consistency between manufacturers, and often from manufacturers. Bottom line is as long as the bullets not unusual, it should fine.
But Im not advocating running 5.56 in .223 chambers, follow the guidance. Im just TOMA the stuff I think is the reality of it.
Just for the conversation. FWIW.
