See Post #4. What it basically says is that the shorter leade in a .223, coupled with a longer ogive GI bullet, CAN cause an over-pressure problem.
The earlier Vietnam-era GI ammo used a lighter, shorter bullet, so it was not a problem in a .223 chamber. That was then; this is now.
If you want safety for using 5.56 current-production ammo in your .223 rifle, get a gunsmith to lengthen the leade to 5.56 spec. That's easy enough.
