CHAMBERS FOR THE 223 and 5

There is little difference between military and commercial 223Rem/5.56NATO brass. Some dealers sell brass that has been "processed"- tumble cleaned, de-primed, and the primer retaining crimp removed. While this saves some work, I have seen a batch of 5.56/223 where the primer pocket was reamed too deeply, leaving the new primer unsupported for half its depth. ................
