That's only the Winchester statement. They are not the only ones who
speak on the topic. Read the SAAMI website. Anybody that tells you
there is no difference between a 223 and a 5.56 doesn't know what they
are talking about. Once again ...... SAAMI states that it is an unsafe
practice to shoot 5.56 in a gun that is only designes to shoot 223.
They are the experts.


OK, but that begs the question "Why design or buy a rifle designed to shoot only
223?". All my experience has been with AR-15s and clones the kids in our club
use to shoot military matches so I didn't know there were two seperate 223
rounds til now (Thanks for the info).
