I love the internet, everyones an expert. For info on .223 Wylde refer to the thread below, Corben1 is the user name of Bill Wylde himself.

Really don't understand why more people aren't offering this chambering, especially with the whole 5.56 US State Dept. restrictions. A match chamber that works well with plain old SS109 NATO and various .223 loadings, seems like a no brainer to me.

Rechambering .223 to .223 Wylde will not increase headspace as every dimension is the same except the leade
It will only remove a very small amount of metal from the Leade increasing jump and reducing pressure. I have a few rifles that have been recut to .223 Wylde as I like shooting heavy bullets, guess what no headspace issues.

I am not saying that this work cannot be done. Obviously it can be. However it isn't as simple as simply running a reamer into the chamber and giving it a few twists.

How do you measure the headspace with the reamer? How do you set the reamer to the correct headspace without going too far and cutting extra headspace? This kind of thing is not a simple job.

Well it is not rocket science. It is finish reaming a hole with a piloted shouldered reamer.

Other than turning it the wrong way and dulling the reamer I am at a loss as to how someone could botch the job?

Pull through reamers for the Garand and M14 are that simple. Could you not apply the same principles to the AR platform?

Not sure any of this matters as most ARs are chambered for 5.56 so a reamer can't be used. Any that are .223 can't be trusted to actually be .223 so it would be best to have a gunsmith cast the chamber and confirm so you might as well have him ream it as well.

Other companies make the same thing.

How do you know how far to go?

You can't just stick the reamer in and measure that as zero because the reamer you are using is a slightly different shape from the one used to make the chamber so you have no way of knowing what part of the reamer has bottomed out.

The difference between OK and excess headspace is only a few thousands of an inch. How do you even know what the headspace of the current chamber is? Maybe it is just on the cusp of being too much and it takes sweet FA to go too far with a reamer.

For all the whinging that goes on this forum about parts quality and not using 556 in a 223 chamber now we think it is OK to run a reamer into a chamber by hand and cut an unknown amount of metal out of an unknown chamber at an unknown angle? Seriously?
