Naphcon -
Not sure if you're familiar with Wison dies, but they're not used in a conventional press. In the old days we used to whack them with a mallet, then I graduated up to using a drill press (not running!). Nowadays, I'm much more sophisticated, and have a nifty little arbor press. Wilson system works very well, but is limited to neck-sizing (steel bushings about 12 bucks). A some point it's likely the case will need to be full length sized, and that's where the Redding Al pointed out above, with a conventional press would be needed...
You may have found out by now that the 220R was originally drawn to use a .221 bullet. I agree with Al that slugging the bore would be a really important first step. It may have a bearing as to whether you choose to fire it or not. My guess is that Sako would have used their standard .224 bore barrels, but that is only a WAG - you can't know for sure without a precise measurement.
Best luck, whatever you decide. Dick
