Anyone here have experience removing a barrel from a Steyr MIII action? This is the one with the rear locking lugs. A friend has one in 25-06 that is shot out and needs a new tube (verified by borescope). I can see the barrel tenon is threaded into the receiver, but it looks as though it's butted up against an interior shoulder in the action and not on the action face. I've been told they are shrink fit, swaged on, etc... and am wondering if it's doable and looking for advice.

Thanks for any info.

Ok, anyone with ANY idea? My one thought was that if I had to, I'd bore out the barrel stub to the top of the threads, face the action off, true the threads, and install a new barrel conventionally. Rifle doesn't shoot worth a hoot right now, and I don't think he wants to send overseas for a new tube.

Your buddy may have no choice but to have the factory do it. Does Steyr even support that model any more?

He said they mentioned something about not having that caliber available for it, but they should have other barrels yet... That's why he wants me to do it if I can. If I can get the barrel off, putting a new one on is the easy part.

Most of the rearlocking steyr rifles has traditionaly treaded in barrels, so most likely no problems.
But a few SSG had a shrink fitted barrel. Where you have to cut the old barrel, turn out the remains of the olt barrel, in a lathe. Then make a new barrel with a cylindric part apx 40mmlong, and about 0.04mm larger than the bore in the action. Then you heat up the action to about 350 deg of centigrades. and then rapidly install the barrel, before the heat sinks and lock the barrel
The mesurements is from my old alzheimer infected memory, so please check in the process.
