Barrel Swap?

[E6Chevron]

Are you changing caliber/cartridge in this barrel change, also?

Have you got an additional barrel extension for use with this new barrel?

Haven't tried anything yet. Still waiting for more specific tutorial, which may or may not be forthcoming. I've changed barrels on several 110s with success. What puzzles me is the feel of a chamber gauge as one approaches correct adjustment.

As luck would have it, the .308 OEM barrel seems to be a good one, but I'm still in load development. Just haven't had opportunity to get it and my ladder test out to the range.

Got the 20" X-caliber CF barrel in lest week.
Did a quick swap from the .260 barrel and took a few pics.
Haven't shot it, but the CF barrel fixed the issue of the barrel heaviness, which was the only issue I had with this rifle.

So did you get a good feel for the way the headspace was set? Did you use a go and nogo gage set or did you use tape on the go gage?

I headspaced it like I headspace all of my barrels, tape on a sized case, but in this case I used blue painters tape instead of scotch tape, as that's what was needed to make it no go before I disassembled it the first time.

So the blue painter's tape is usually .005" and a "standard" nogo gauge is .005" (.004-.006). makes sense. I've only used magic tape for conventional lugged actions and the ejection pin removed from the bolt.

This headspace check was done without having the extension installed in the receiver, correct?

The locking/unlocking action is done by rotating the handle forward or rearward, so that should be enough for the floating bolt head to engage the barrel extension, I would think.

Nope, extension is installed in the receiver.
Then you screw the barrel into the extension until the bolt doesn't close with the taped/sized case, but does with an untaped/sized case.
Apply some blue Loctite, Tighten barrel nut, check headspace again, go to range.
Same process as a non extension receiver.
