Along the way I picked a CZ550 barrel in 9.3x62. I've also got a Mark x 98 action, the wheels are turning. So the question is, will the two mate with minimum expense or should I just shop for 98 barrel?

The threads are different even though they look the same. If you want to actually talk about a 9.3 barrel and fitting them to Mauser actions, PM me.
It will also depend on what you mean by "minimum expense". Mauser are 12 tpi, English threads. CZ 550 is metric, close but not close enough. Like 2mm. Both 1.1 inch OD.

Thank you, my curiosity is satisfied.

The tenon of your CZ barrel could be sleeved and threaded for the 98. Regards, Bill

cut off the tenon, remachine to work in the mauser, gives you the sights and built in hardware on the barrel - all in, this might save $200 bucks on a rebarrel built out the same - BUT will cost more than buying a 9,3 on a new, slick top, barrel

You don't have to cut off the tenon; unless you just want to do it. Regards, Bill

Would you please describe your sleeving method?
I have personal experience with a sleeve that was soldered on with Force 44. The barrel gave good service for several years, then the solder failed. The barrel, less the threaded sleeve, was shot out of the receiver & sailed down range. There was no damage to the firearm or shooter, but the experience soured me on sleeved high power barrels. Thank you.

Yes, it got the shooter's attention for sure. It also got my undivided attention when the shooter called me. This was about 25 years ago and was the result of an attempt to salvage a new Hart barrel that suffered a machining flaw. Since then, I have stayed away from sleeved barrels like the plague. It's easier and much better for morale to "eat" a $300 barrel than to turn out questionable work, no matter how good. the intentions.

Sure. In the first place, force44 doesn't work very well on stainless. If I was going to attach a sleeve via any sort of solder, I would use high temp silver solder. The truth is though, I wouldn't do it though I have seen it done.
Taking this particular barrel as an example, I would turn the tenon to 15/16" and thread it 20tpi. I would then bore and thread a sleeve to a close fit on the tenon and install it using loc-tite or epoxy. Then it is a simple matter to thread the sleeve to fit the action. It is even possible to move the barrel shoulder to establish headspace or, in the case of a mauser, to face the sleeve to the appropriate length.
I can't guess how many barrels I have fitted to various actions this way. I have also used sleeves intalled this way (but minus the loctite) to time a barrel so the sights are on top or to adjust headspace (just like on a Model 12 shotgun).
Interestingly enough, I have, on my bench right now, a CZ barrel which I fitted to a Mauser 98 just this way.
I once worked in a shop where there was a gunsmithing course put on for hobbyists. Now and then, one of the students would mess up a threading job and bring it to me to fix. For smaller tenons than the Mauser, I used to turn and thread the tenon to 7/8x14 and use a grade8 lug nut for the sleeve. On some chromoly barrels, I used soft solder instead of loc-tite to secure the sleeve. No particular reason; just whim.
As I said, I have seen sleeves soldered on with high temp silver solder and I suppose that is just fine but I really prefer a mechanical interface. Regards, Bill
