.223 Wylde ???

IIRC it is cut to allow both .223 and 5.56 to function properly seeing as there are slight differences between the two in dimension.

RRA uses a Wylde Chamber and I know Arwen Ace has the proper reamer. I have used a rifle chambered so and it was extremely accurate.

Bill Wylde is a friend of DCRA shooters across Canada, and he lives in Illinois. He read the drawings and thought there was a better way to shape a chamber. Not a big difference in dimensions, but apparently a big improvement in accuracy. Google him and see what comes up.
 
RRA quotes the Wylde chamber as follows:

"The .223 Wylde chamber was designed as a match chambering for semi-automatic rifles.
It will accomadate both .223 Remington and 5.56mm NATO ammunition. It is relieved in the case body to aid in extraction and features a shorter throat for improved accuracy."

Regards.
 
What has become known as the Wylde .223 chamber was designed with several uses in mind. One of those uses was Canadian IVI 62 grain (C77) NATO ball.

Although you may read that it is a new chamber design, that is not the case. Ten minutes on the phone with Keith Francis (JGS reamers) created this chamber in 1984.

The basic chamber was from one of two NATO prints. Can't remember which one in my old age. The freebore was ground to .2240", which provided a good seal for a short-seated bullet. This smaller than NATO spec. freebore lengthened the freebore enough to allow the 80 grain Sierra to be used at about 2.470-2.475" OAL.

We just got lucky. Enjoy!

There you have it right from the man himself. Hi Bill:wave:
 
Hi, Tom,

Great to hear that someone is getting some use out of that old chamber.

Terry was right.....Just Google that chamber and start reading. Boggles my
mind!

KevinB mentioned Mk262. I had no idea what it was. A good bet is that his rifle has a full length gas tube to shoot that bullet well. Just a guess from a little project I did for the Navy a few years ago.

Please pass along my good wishes to the crew.

Bill -- actually a Midlength gas system 16" done for me via KAC, and Armalite midlength and not KAC middy - aren't I special ;) .
It's got 18k+ and still going strong (pretty good for SS barrel) However I noticed recently is more of a MOA barrel than the laser it was when young.

The Camp here has a good weapon shop for people in odd places and I am looking at getting it rebarrels (need a shop to drill the bbl for the KAC front sight gasblock). I just wish that DOS/DHS was not so anal about shipping stuff to Iraq.

Nice to meet (albiet electronically) the creator -- Thank You Very Very much

-Kev
