My understanding is that it falls right between a 5.56 and .223. I believe the difference is the depth of the throat. 5.56 being longer to allow longer tracer bullets, and 223 being shorter to enhance accuracy.

If .223 is "tight" and 5.56 is "loose", then Wylde falls in somewhere in the middle. It is supposed to give you the flexibility of the 5.56 chamber, while maintaining some of the accuracy of a tighter chamber.
The difference is in the throat area of the chamber, with lead angles and such differing slightly. |

The Wylde is the same in the *body* as the NATO chamber. It does have a shorter throat than NATO.

Will this chamber still shoot all of the .gov ammo like M856 tracer?

as you can see, the Wylde has a large body to accomodate milspec 5.56mm ammo, but a somewhat short throat and shallow lead angle. The idea being to function reliably with everything (hence the loose chamber body) but maintain good accuracy with match grade rounds. (hence the tight throat.) I have an RRA A4 with this kind of chamber, and it's never jammed, even with crappy eastern bloc surplus junk from gunshows. On the other hand, it managed decent groups with nicer stuff. |

I have no idea about the dimensions of my Wlyde chambered RRAs, but I do know that they feed and extract M193 and M855 just fine.

After building my own SPR clone I became great believer of Wylde chamber. Best 5 shot group so far with my SPR is 39 mm (1.535") @ 300 m with Sierra 77gr Match King. Of course, barrel itself has something to do with it, too.
