It's still using ammo in a firearm marked for a different ammo.

If one wants to take that risk personally, fine. Advising others to do so, IMHO, is a bit reckless.

Clint McKee of Fulton Armory (fairly well known as a knowledgeable guy in the firearms field) describes using shooting 5.56 in a .223 chamber as "Very Dangerous". It's not just pressure levels, it's the depth of the lede.

SAAMI to this very day lists shooting mil-spec 5.56 in a .223 marked firearm as an "unsafe arms and ammunition combination": SAAMI | Unsafe Arms and Ammunition Combinations
