Started this post in the ammo section, just realized it needed to be moved here to reloading.
As stated in a couple of my previous posts, I am new to the AR community and am looking to build an AR 15, likely chambered in either 223 or 223 wylde. I am still educating myself on everything in general but am now most curious about the 223 wylde ammo and what it takes to hand load it. Can someone explain to me how this is done? Do you start with a typical 223 casing and re-size or is it more complicated than that? Below is a reply I got from the first post in the ammo section. That said, can someone explain to me what the 223 wylde is? What is the purpose of having the wylde chamber if your shooting typical 223 or 5.56 rounds? Sorry for my ignorance, I'm just not familiar with this. Thanks. Quoted:
No resizing needed. A civilian pressure 223 or a military pressure 5.56 round will both function in a Wylde chamber. |

223 Wylde is basically a 5.56 chamber just a bit tighter than usual for possible increased accuracy. I have an 18in SS barrel 1/8 with a Wylde chamber and I load LC brass to 5.56 pressures behind 77gr SMK and it shoots great.
I'm quite confident that if you are not going to shoot 5.56 spec ammo a good 223rem chamber would prove best for accuracy. The Wylde is between the 223rem and 5.56. There is no actual 223 Wylde ammo, it is designed for 223rem or 5.56. |
| In general, I think the distinction between 5.56, .223, and .223 Wylde is way overstated. Load up .223 ammo as you normally would, to achieve the velocity you want out of your rifle, pay attention to what your brass is telling you, and you'll be fine. In all cases, you'll need to exceed book listed maximum loads to see any issues between the two. Most highpower shoots go way above book-max, and are shooting in .223 Wylde chambers or similar such tight chambers. You're going to be fine. |

The only difference ive really noticed is all my guns chambered in 5.56 are a little "looser" in the chamber than my .223 wylde barrel. ive had a handful of rounds not chamber in my .223 wylde but fit in my 5.56 guns. a buddy shot a box of pmc bronze in his .223 wylde and 4-5 wouldnt chamber. I bought a lyman headspace guage to check my match ammo for the wylde. |
| I'm using Noveske barrels which have a "5.56 match" chamber. It will shoot just as accurate as .223 wylde. I've never had an ammo problem with it and I reload the majority of my stuff. Like the other guys said, the .223 wylde is over-hyped and probably not worth your time. I have 3 Noveske barrels and will continue to buy them for my builds. They are fantastic barrels. |

I've read claims that many of the 5.56 reamer drawings currently in use vary widely insofar as how loose (compared to .223 Rem or Wylde) their dimension really are. My one and only 5.56 barrel (Green Mountain 20" govt profile, 1in8 twist) is extremely accurate with a .223-level load (52 grainer at 3050 fps). Since I size my brass about .004" shorter than fired at the shoulder, the case itself is a fairly close fit in its corresponding chamber.
The other important dimensional differences between the two specifications are the length and diameter of the throat. That is the section the exposed portion of the bullet sits in, aft of the tapered start of the lands. The military likes to have a fairly long throat, or freebore, to allow for hotter ammo and accumulated fouling. IMO, the length of the throat is not particularly important to accuracy, instead its the diameter of the throat that matters. M4 carbines (pure milspec chambers) are not known for their accuracy. I don't have the means to measure the diameter of the throat in my GM 5.56 barrel, but I'm guessing its tighter than the NATO standard .227" - CW  " />
