I want to order a case gauge for my 3 ARs. One is 7.62, One is 5.56, No problem with those. My third is .223/5.56 Wylde chamber. Does that take a seperate gauge due to the chamber being slightly differant? I looked on Brownells and they had one listed that said .223/5.56 Wylde. So that threw me off as to if it takes a specific gauge. Barrel is a new Wilson stainless, 20 inch. RRA Predator. Reloading on a Redding Big Boss and national match FL dies.

I use a regular .223 case gauge for all three chambers. The Dillon gauge works great.

For future reference, all three chambers use the same specs for cases. (.223 / 5.56mm / Wylde)

IIRC, the differences for a Wylde are in the throat - lead angle and freebore. The chamber, shoulder and neck are no different.

You can look it up online.

Looking at this diagram it looks like the chamber is differant?

I could have saved you from buying the first. And I have all my fingers intact.
