Cam, it wouldn't be that hard to do if you're doing it yourself. I've done basically the same thing lots of times except for bushing the bolt face down for guys wanting to go from sliding plate extractors to Sako style extractors for more positive ejection of PPC cases. The first thing to do would be to plug the sliding extractor slot with a piece of steel milled to fit into place. I mill it to where it's a slight drive in fit. Then bore out the front end to clean up the leading edge of the extractor plug. No need to bore it out any larger than the magnum bolt face or you could bore it out a little over the magnum bolt face to make sure and clean up any chamfer at the front of the bolt face. Then make a bushing to just slip in the bored bolt face with the inside of the bushing bored to .010" over PPC case head diameter. JB Weld the bushing in place. If your bolt has an ejector pin, it will need to have at least part of the ejector in the new bolt face. I'd go about half in and half outside of the bolt face if you can. It's possible to plug the ejector pin hole and move the ejector location if needed. That will help with not having ejector markson your fired brass. It would be better if the bolt originally didn't have an ejector pin drilled in it as it just makes more work if you have to move it. Set up your bolt in the steady rest with your compound parallel to the front of the bolt cone and face off the front of the cone on the bolt to clean up the plug and the bushing. Set the compound to put a slight 60 degree chamfer on the front edge of the bolt recess and then you'll be ready to mill for the Sako extractor. Bat sells their extractors for about $35 or so. I've done similar before including the bushing, but it's been going from a BR bolt face to a PPC bolt face. I've plugged probably about 30 sliding plate extractor bolts and installed Sako style extractors in them for various competitors, several for Charles Huckeba and others. I was doing it for friends so wasn't concerned about the time it took and was just charging a minimal amount. As long as you are doing it yourself, it's worth doing as long as you realize that it will hurt the value of the bolt, action and rifle. But, it's one of those things form follows function. If you can win with it, minor flaws in looks don't matter all that much. It will be a job, but can be done and probably quicker than getting a new bolt from Bat. A new bolt would be better, but with your location might not be feasible.
