| Ok, this may be a stupid question, but here goes. I know the difference between chamberings in 556 & 223, but what is the 223 whylde chambering, and what ammo is safe to shoot thru it? |
| Target shooters need a chamber that is as tight a a SSAMI .223, but lets you load to a longer OAL. The .223 Wylde chamber has a longer throat to allow you more flexability in using heavier bullets. Unless you are using your rifle in NRA high power or some other form of competitive shooting, you are better off with a NATO 5.56 chamber. My target rifle has a standard SSAMI .223 chamber and haven't had any problems with bullets up to 77gr when loaded to .223 OAL. You should be able to fire any commercial or surplus .223\5.56 ammo through a rifle with a Wylde chamber. |
The 223 wylde chamber was designed to be a reliable auto loader chamber and is not a tight chamber with the exception of the free bore diameter. The base diameter is right on par with the NATO chamber and the neck diameter and neck length is larger and longer than the NATO chamber. The big difference is in the throat, it has a longer free bore (.0619” v. .0566”) and a much tighter freebore diameter (.2240” v. .2265-.2267”), gotta love that friction fit for accuracy. In many respects it's more of a modification of the 5.56 NATO chamber than a SAAMI modified chamber. Ref IMO the wylde chamber works well as a alternative to the 5.56 NATO chamber both in reliability and approximating the same pressures, but it's a more accurate chamber because of the friction fit of the freebore. |
That is not so. Stiles posted the correct information regarding the 223 Wylde. |
| I have a Fulton Armory that has a Whylde chamber that is marked 5.56, very accurate rifle. Fulton states that you can shoot any 5.56 or .223 in there rifle. There F.A. heavy barrel marked "FA MP 5.56MM CHROME 1-9" is made by Dougles. I had mine chrome lined. They also do not butcher any of there military parts, unless they have to comply with a law or two. |
It's named after its designer, Bill Wylde. |

It's pretty amazing that Bill Wylde slapped together this chamber back in 84 and it's still as relevant as any chamber that is appropriate for the AR. Here is a post from Bill Wylde that some may find interesting:
