Steyr actions?

A friend of mine is wanting me to rebarrel a steyr he has. It's a 25-06 with 1500+ rounds down the tube and the throat is gone for a good inch. Has anyone here ever removed one of these barrels? This is one of the rear lug Steyr actions (MIII I think). In looking it over it appears to have no shoulder on the barrel at all, just a tight abutment inside the action at the rear of the thread shank, like a M98 mauser (except for the missing front bearing surface of course). I believe he had talked to a rep and they said something about a shrink fit in addition to the thread. If that's the case, I won't even attempt it.

Any ideas?
 
Maybe one of the Euro shooters has some specific insight.

If a factory installed bbl gives me even a hint of trouble I break out the propane torch and carefully heat up the receiver. With propane you would have to try real hard to overheat the rec. If it was still tight I would hold a 'canned air' aerosol upside down and squirt some super cool gas into the chamber end of the bbl to quickly shrink it.

I have a motorcycle mechanic background and many operations require the proper application of heat such as removing and installing ball bearings in the engine cases, installing the crankshaft into the bearings, etc.
 
I think Steyrs are a press fit and require specialized mandrels for replacement with a hydraulic press. I also believe that it is possible to bore the old barrel stub out of the action and then install a female thread for conversion to a conventional setup. I'm out of my element here so consult with an expert before charging forward.

I can see barrel threads through the front action screw hole, I know the barrel is threaded into the action, I just don't know the class of fit I guess as far as interference.

Thanks for any insight, I suppose I should really call a Steyr rep.
 
msalm,

I googled up a description of barrel fit and a review on snipercountry describes a 57mm long threaded barrel shank (that I think is screwed in to correct headspace) and then crimped in place by swagging the receiver ring around barrel shank. Faster to mfg than even a Savage but a B**** to replace. At least I remembered correctly the need to bore out the old shank from the action. Sorry I misdirected you.
