a wealth of information. thanks for the data and history lesson. I have it bookmarked for reference.

Thanks for that. Having been a shooter during those times, of draft age, and with Viet Nam ratcheting up, I remember the squawk about the original issue rifles NOT being chrome plated as was designed by Stoner. Their high failure rate in the field left a lot of bitterness back then.

Also the idea of a tumble-upon-impact bullet seemed, well, rather unsuitable for routine civilian use.

thank you

Wow. I really appreciate that. I can't tell you how many other articles I've read that claimed to explain the difference but then completely failed to do so. Your article makes things clear.

I do have one question, though. I've been seeing some AR-15's lately that have ".223 Wylde" chambers. No one I have talked to seems to be very good at explaining what that is. How is it different from .223 and 5.56 chambers? Does it have any advantages?

ditto1958, In the article, I said: "Basically, a Wylde chamber is a favorable mix of a 5.56 NATO and a 223 Rem chamber where any 223 Rem or 5.56 ammo will fire safely and accurately. 5.56 NATO chamber can be reamed with a Wylde reamer to relieve the base diameter. 223 Rem chamber can be reamed with a Wylde reamer to extend the leade."

A Wylde reamer is longer in the throat than a 223 Rem so it will allow the chamber to accommodate a slightly longer bullet ogive like found in 5.56 NATO ammo. The base of the reamer is a thousandth or so larger in diameter than a 5.56 NATO chamber so it will allow a 223 Rem cartridge to chamber without binding on the base.

Thank you. I must need better reading glasses- or a better memory- cuz I sure did miss that somehow. I'm going back to re-read the article.

Good post. The amount of "free bore" in the 5.56, is greater than the .223 Remington. People need to understand that when you shove a 5.56 into a .223 chamber, that bullet is dangerously close to the "leade" on the rifling. Some can even be touching, creating a huge pressure spike.

Thanks for posting! An excellent lesson that happened to clear alot of things up.

Fantastic!

Thank you, once again!

I need to order a new sizing die and now I know to order a 'small base' for my two Stag ARs.

Thanks. Once again you've come though!
