Following on from a previous thread on takedown rifles, I've become intrigued by an idea. How would I go about rebarrelling a Mannlicher-Schoenauer 1903 or GK from let's say 6.5 x 54MS to for instance 7mm08? There are plenty of MS rifles out there available for maybe £300-£500, possibly with slightly decrepit barrels. Supposing I found one with an action and stock in good condition, it should be possible to have it rebarrelled to a modern calibre, but I have no idea how to go about this technically and legally, or indeed a very good handle on the true cost of such a project.
Legally, would I need FAC slots both for the 6.5x54MS and the 7mm08? Or could I buy the original MS rifle off ticket on the grounds that it's an obsolete calibre, then add it to the FAC after it's been converted.
Where would I find a barrel? Obviously MS never made a barrel chambered for the 7mm08, even if you could find one in the white, so what is technically involved in adapting it, or are we talking about a completely custom-made barrel?
Do barrels on their own have to go on an FAC (I think so, as they're a part if a firearm)?
Finally, how much does a barrel, its' fitting, rebluing, possibly some reconditioning on the action etc, cost? I'm not expecting exact figures, just some sort idea of scale.
This is probably one to put on the longer-term projects list, but I really have no idea, and I'm pretty sure that some of you lot do.
Thanks for your help!
