The Dunning-Kruger effect is alive and well.
The Extractor used ls the same. There is only one Extractor for all bolt bolts. The difference is where the hole for the Extractor Ball & Spring is machined. Below I included pictures of the 223, 308 & 300 WinMag Bolt Heads. Where the extractor ball & spring hood is located dictates where the Extractor stays positioned.

To be honest, I would just order one of these kits anyway. They are worth it!

I changed my Axis from .223 to .308 and used the .223 extractor. Works for me. But...I don't use the ejector nor do I load from the magazine, so I can't say if those functions work or not. It is short enough to not hang out over the edge.
I can say I've had to force the bolt open a couple times and the ejector was strong enough to rip the rim off a .308 case. :)
The bolt shroud might not present a problem. If the bolt doesn't go back as far as you want just rotate the baffle 180deg and put it back in (at least that's the way it works in an Axis).
There is only ONE Extractor sold. Below is the factory OEM parts Bolt Head kit sold at Gunshack. It states these are parts for all 10/110 Bolt Heads. Again, it’s the Extractor Spring/Ball retention hole position in the Bolt Head that dictates the position of Extractor.
