.223 Wylde Chamber?

i see a lot of stainless match barrels have .223 Wylde Chamber, can you shoot 5.56 in .223 Wylde Chamber?

In most cases yes. But I have seen some .223 Wylde barrels have some problems with 5.56mm NATO but that's a very small amount.

I have a White Oak Armament 1x7 .223 Wylde chamber on my 3gun rifle and it shoots 5.56mm NATO without any problems.

What he said. My LT Stealth upper will various 5.56 loads fine. Of several RRAs (all Wylde) some will, some won't.

I have an 18" SPR barrel with a Wylde Chamber. It's a SS Douglas Blank cut by Compass Lake.

I have only been shooting 77gr. Black Hills Through it. I had one failure to extract in my first 5 rounds. I have not had any problems after that. I still have no idea why it happened.

I think it depends on who you buy it from.

LaRue Stealth upper is Wylde chambered. Mine shoots 5.56 just fine.

why they use .223 wylde chamber, instead 5.56? what's the advantage?

Tighter chambers mean the gun has more accuracy potential. You also get slightly higher pressures with a slight velocity boost.

It's popular to use Wylde chambers in builds where there is a high concern for accuracy, as in match or varmint builds. White Oak is one place that uses them, another is JP, and another is Rock River. There are a number of makers who use them. I think these chambers give you a bit tighter tolerances (and thus potential for greater accuracy), but still enable you to use standard 5.56 when you want.

Found this on another forum. Attributed to Bill Wylde:

"The case dimensions of the Wylde reamer are that of one of the NATO prints. Not a thing tight about it. As I recall, there were two NATO prints in use. I don't recall the print number used, but do have it in old records somewhere.

Throating was about the only change. The decision was made to make the freebore diameter .2240" as a good bullet seal. That done, excess freebore made little difference to accuracy. One of the reasons the magazine length 69's shot so well in the chamber. It so happened that the 80 grain Sierra seated to the lands was about ideal at .2470" OAL. Simple luck.....All of it.

The initial reamer(designed in 1984)was mainly geared toward Canadian 5.56 ball, as I was experimenting with their issue ball for competitive purposes. This operation was slow in getting off the ground, and really didn't start happening until about 1990. The use of 5.56 NATO ball in Canada was a short lived affair. Handloads were allowed in about 1994."

Not to hijack the thread, ... but can anyone comment on (or clarify) the difference between the Wylde chamber and Noveske's MOD O chamber.

As I understand it, the Wylde is a ".223"-based chamber, whereas the MOD O chamber is a "tight" 5.56mm chamber, i.e, tighter than a normal mil 5.56mm chamber. Correct? Thanks.

My understanding is that the Noveske is on the "tight" side only in the neck area and is on the "loose" side of spec in the body. This is said to give most of the acuracy advantage of a tight chamber but also helps with feeding over a "normal" tight chamber.

This may be incorrect info as I can't actually recall where I heard it. So take it with a grain of salt.

Thanks for the info anyway, Dr. :)
