.223 Wylde Chamber?

The Wylde chamber has a much longer leade than a SAAMI .223 Remington chamber. If I'm not mistaken, the Wylde chamber was originally made to shoot extremely long ojive, heavy bullets out of the AR.
 
Yes, that is a bi-product of the Wylde chamber, but not what it was created for. From memory, the Wylde chamber is basically a match chamber with a very long leade. The 5.56 chamber has a fairly long leade as well, but has a different leade-angle and a sloppier neck and body.
 
The RRA Varmint rifles come with a Wylde chamber, which is a mix between .223 and 5.56. For those of you that do not know, the 5.56x45 NATO is NOT exactly the same as a .223 Rem. The 5.56 spec allows for slightly longer chambers for HIGHER pressures. The .223 has a tighter chamber around the neck and is shorter which allows for a bit better accuracy. You can shoot .223 ammo in a 5.56 chamber, but it is DANGEROUS to shoot 5.56 (surplus for instance) ammo in a .223 chamber. What the Wylde chamber does is allow for 5.56 ammo with slightly tighter chamber for better accuracy. So you can shoot both 5.56 and 223 safely with good accuracy.

The "Wylde Chamber" (for competition-use AR-15 pioneer Bill Wylde) is 2.445"; the "AMU Chamber" (for U.S. Army competition team) is 2.500".

I use the Wylde chamber in all the AR 223's I build except the 1/4" guaranteed AR 15 rifles I build, in which I use a Carey spec'd reamer. /ubbthreads/images/graemlins/grinning-smiley-003.gif




After reviewing my reamer prints it appears my reamers are a modified Wylde design.

I have been researching the possible purchase of a RRA A4 for some time. But now I'm a bit confused. /ubbthreads/images/graemlins/confused.gif I have the Rock River catalog in front of me. It states in part, "the Wylde chamber was designed as a match chambering for semi-automatic rifles....and features a shorted throat for improved accuracy"

I do beleive leade and throat can be used interchangably. I'm curious to the correct answer because I personally don't want a gun (chamber) that has to have the long bullet sticking out for top accuracy.

Rock River has a well deserved reputation of being one of the most accurate AR 15 rifles made in the country. They use the Wylde chamber as does a few others. I like it, or I wouldn't use a modified design on the match grade rifles I build. /ubbthreads/images/graemlins/grinning-smiley-003.gif

The Wylde chamber has a very long leade. It was designed to shoot 80gr bullets single loaded in 1000 yard competition. By using a long leade the bullets could be seated very long which increases powder capacity. If you intend to load any ammo in a magazine, the last thing you want is a Wylde chamber.

I have a RRA Varmint with the Wylde chamber. It shoots regular .223 ammo fine and it runs through the magazine with no problem. I have been using regular .223 dies to reload for it and they seem to work fine. Should I buy a set of Wylde dies or stick with my old .223 dies?
 
Do you have any dimensions on the different leade's?
As in how long the SAAMI 223 leade is and how long the Wylde is and the 5,56?
If so post them. I have a different opinion.

Yes, I have the chamber prints in front of me.

The 223 has a .025 leade with a 3-10-0 throat angle.
The 5.56 has a .0565 leade with a 1-13-24 throat angle.
The Wylde has a .0619 leade with a 1-15-0 throat angle.

Why they specify dimensions more precise than any reamer grinder could exactly match, I don't know?
