223 Wylde Chamber Question

[Ken]

I am having my prairie dog rifle rebarrelled. It is a Rem 700 223. I shoot mainly 55 gr vmax bullets. I have purchased a Krieger 8T barrel in light varmint taper. One gunsmith suggested a 223 Wylde chamber, I understand it has some larger dimensions than a SAMMI 223 chamber.
Will I run into problems using my reloads for this rifle in my AR 15s or perhaps other 223 rifles. If I got a short throated, standard chamber would my accuracy hold up longer with this bullet than the Wylde chamber? Any thing else I should consider in the new chamber?

Hey Ken about a year ago now I built a .223 Wylde on a Rem.700 to prairie dog hunt in Wyoming in the Gillette area
I only used the Wilde chamber reamer because it’s what I Had on hand and the barrel was a 7 twist pac-nor. do your own research but I believe the only difference in the two chambers is the throat area is a bit longer but it’s tight .224 I believe so keep it clean! if your not planning on shooting 5.56 ammo I would choose a regular.223 chamber . I shoot factory 5.56 in mine but it’s not accurate at all especially for prairie dogs at any distance. The whole idea of the Wylde chamber was to make it possible to shoot both .223 rem. & the slightly hotter 5.56 round in the same rifle. if I had it to do over I would have purchased a good .223 match reamer for that rifle build.

Isn't the freebore in the Wylde also tighter than in the 556 chamber? My understanding is the tighter freebore is supposed to provide more accuracy.

Also, wouldn't the Wylde chamber enable higher pressures/velocities => flatter shooting?

 

[std7mag]

From my understanding, the Wylde chamber has a longer freebore/throat than the standard 223 Rem.
I think (don't quote me) that the angle may be different where the lands meet the throat.

It won't necessarily add pressure/velocity, as make it safe to shoot the higher pressure 5.56 rounds.

 

[jelenko]

I was thinking that the Wylde chamber enables you to use 556 level pressures [i.e., ~ 60K vs the 55K SAAMI limit]

 

[urbanrifleman]

The Wylde is simply a barely changed knockoff of the old Army Match Team Reamer from the 1990s (a thou here and there changed). It is the chamber that works well for everything from 40 grain to 80 grain bullets. For some reason people really liked the name and it became very popular.

That is correct

 

[urbanrifleman]

See for yourself. The Wylde is kind of a compromise. Really, as far as I am concerned, most of the 223/556 discussions are much ado about nothing.

The biggest differnece between the old "223" and the NATO 556 is the freebore.

 

[Ken]

I found this discussion and it sounds like I would be happy with the Wylde Chamber, just not sure about reloads,
The .223 Wylde is a hybrid .223/5.56 chamber designed by Bill Wylde to yield the accuracy advantages of the match .223 Remington commercial chambering, but without pressure or reliability failures when using high velocity 5.56 NATO spec ammunition. The .223 Wylde achieves better accuracy by having a chamber throat that is tighter than 5.56, but will still function reliably with military 5.56 ammunition because the case dimensions are the same. These facts lead to the .223 Wylde having superior target and varmint accuracy, a compatibility with all .223 and 5.56 NATO ammunitions, and being a top choice for competition shooters.

 

[Ken]

How about reloading the brass after shooting it in the Wylde chamber?
Is it as simple as running it through the 223 full length sizer and shooting it again or would there be possibles problems especially if I want to shoot it in a different rifle?. I use a Dillon carbide 223 sizer and don't want to buy something different. Would it shorten brass life?
The above chart shows a slight difference in the shoulder/neck between the Wylde and Sammi 223 chamber.
Which of the above is closest to the Rem factory chamber?

Brass is fl sized the same, 223 or 5.56. But all brass may be a little different. Its all most impossible to pull the expander thru some brands of lubed necks. Neck turning fixed it for me. A bushing die may work better then a standard die. The bushing doesn't need to size all the way to the shoulder/donut.

Rem factory chamber

See SAAMI standards https://saami.org/technical-information/ansi-saami-standards/

 

[urbanrifleman]

I am saying this in love, you are overthinking it bro.

Wylde is a 60ish freebore Rem 223. I had all my .223 prefit barrels made with the Wylde reamer, and the 223 Ackley reamer is almost identical to that (Ackley already set his freebore to 60ish FB about a million years ago). The military went to a longer bullet when they went to NATO standard ammo so they increased the FB. There has been a billion Rem 223 rounds fired in NATO chambers.

I can honestly say that the INTERWEBS has genuinely created a black hole of confusion around this issue.

SAAMI- Shooting factory ammo.

 

[Ken]

I think I get the difference in 223 marked factory rounds and 556 marked factory rounds. Seems to be one of higher pressures in the 556.
I'm still not clear on the dimensions of a case fired in a Wylde chamber and in either a factory Rem chamber or a 556 chamber. I understand that a 223 chamber and 556 chamber are the same and the Wylde is slightly different. My concern now is reloading the brass if it is fired in the Wylde chamber.
Regarding overthinking it, yep, I have noticed that about myself. I seem to go through a chaos phase of collecting information about any subject I am studying then slowly sifting through it until I come to a conclusion that satisfies me.
Thanks for the patient responses to this over worked subject.

What problem are you trying to solve? I think you are creating one where none exists.

If you are reloading, then the entire discussion is moot. As you will set your ammo to the freebore. The only real changes are in the freebore, the rest of the dimensions are "in the noise". Some have slightly bigger necks, but the dies for reloading both are the same. Bushings for the neck are set to the brass type you are using, not the chamber.

 

[Ken]

Seems the Wyle chamber is designed to accomodate longer bullets. I want a chamber that will start out ,at least, accommodating 55 gr bullets seated to 2.260 max. I don't single load, I use AICS mags.
Thanks for your patience

 

[Liven The Dream]

Two Points.
Bill Wyle came up with that Reamer for AR's and 80gr. Bullets for Slow Fire 600 yard shooting.
Won't fit in Mag , enter Bobsleds .

Good Barrel Fitter ( Now Pasted) also from Wisconsin . Had a Dog Shooter wanting a Short Throat in a .223 Bolt Gun.

He gave the Customer just what He asked for.
The Rifle Shot like dream.
Fellow came back from His South Dakota Hunt very Happy.
Checked the Throat to find it Move out some .030 ??
Barrel Fitter called His Friend Boots ( Obermeyer ) they had a discussion on the Matter.
They came up with, well that's where the Throat would have been without shorting the Throat.

White Oak has a lot of Chambers for His Different .223 Barrels
I would think His Varmint Reamer would work ???

 

[DR_2297]

If one was going to concentrate on light / short bullets I would seriously look at the Compass Lake chamber. It’s a tad tighter in the body and has a freebore like a SAMMI 223 with a shallower leade that allows for firing high pressure (NATO) type ammo.

when it comes to service rifle competition the two most popular chambers where 3/5 to 3/4 of the match is fired with mag length ammo are the wylde and CLE.

I have shot a lot of rounds through both to 600 and either one will get the job done with room to spare when it comes to pressure limitations. Much of the ammo we fire can often be rated in Hiroshima’s.....

 

[urbanrifleman]

30 FB would be good. Heck zero would be good too, but I find that most of the varmint bullets like to jump. Some as much as 45 thou.

My Ackley has killed about a million pdogs (obvious exaggeration. ) with 50 and 55 grain bullets. Its 60 fb and I can get 22-250 velocities.
