I'm with tobnpr on this one. Retire the '95 and just buy a M/N.
You are potentialy looking at close to a $1000 bill on that '95 conversion. The barrel $300 and reamer $100 (plus all the barrel work the smith needs to do and reaming the chamber) are going to get close to knocking on $500. Then there's the work on the bolt ( I don't know of one which will work "off the shelf" since it's a rimmed cartridge.) The smith is going to have to machine the face larger, rework the extractor. Then there's reworking the magazine so it will feed, unless you just want to go with a single shot insert.
Finally, you're looking at bluing or some type of finish ... plus a bunch of "incidentals" I didn't mention.
Now don't mis-understand; I've had my favorite smith build me a couple dozen rifles over the years and since I'm not dead yet, we aren't done building rifles. But, if you are bothered by the "expense" of 7 X 57 Mauser ... you're "carrying coals to Newcastle" with a custom build. Just buy a nice Mosin-Nagant in 7.62 X 54R and enjoy yourself. You can buy the rifle and more ammo than you can carry for the price of that custom build.
Maybe someday you'll find some more 7 X 57 at a good price. Maybe you'll get into reloading and then you can have all the 7 X 57 you want for a reasonable price. Buy the Mosin-Nagant and be happy. (Hey, if you can find a nice Finnish Model 39 ... you can't possible do better. Great rifle, great sights!
