Yes, I did try a search. That was my first step. I even spent an evening looking through the internet and not just this site.
I couldn't find what I needed.
I even went to the current importer to see if they offer out of warranty service work on the Scout, no information listed there, and FR Frog's Scout site is not working right now. Though I have tried every combination of searches to get to cached copies of info from his site through Google, no luck.
The scout uses the SBS, which was introduced in the late 90's, much later than the SSG. I'm not sure if it's a press fit too though, it's entirely possible. I'm cobbling together info from a couple pages that I admit I haven't read in their entirty yet. They might not give that particular tidbit. Here's the site and pages I'm getting my info from, you might get a lead there if you head that way and I'll get back to it and read closer when I get a chance:
The barrel’s method of attachment to the receiver is unique. First, there is an integral cone machined into the chamber-end of the barrel. In front of this is an aluminum ring (longitudinally slotted for tightening) with an opposing interior cone on each end. Another counteracting ring with a cone goes in front of the aluminum ring. This is followed by a locking nut. Using a special wrench, the locking nut must be torqued to Steyr specifications by a trained armorer only. A rectangular steel locking wedge on an aluminum block attached to the underside of the receiver further secures the barrel. The barrel is completely free-floating and the barreled-action is held to, and bedded in the stock by means of two aluminum pillars in the stock.
A steel lock bushing (or barrel extension) at the chamber end of the barrel permits the use of an aluminum receiver, an important factor in keeping the complete package under 7 pounds. Made from a 6061 T6 aluminum alloy extrusion, the receiver has been black hard-anodized. With the bolt locked in battery into the lock bushing at the end of the barrel, the receiver, in essence, serves only as a framework for the barrel and bolt in a manner reminiscent of the World War II German MG42 General Purpose Machine Gun.
Sharpshooter, try http://www.steyrarms.com/index.php?id=89 and choose the one closest to you. The rifle would be sent back to Austria unless they have the equipment and expertise 'Stateside - which I kinda doubt, since relatively few rifles would require rebarreling in a given year.
