the 220 Swift is actually the old 6mm Lee Navy semi rimmed case necked down to 22 cal,it isnt anywhere near as big a case as the 6mm Rem,,it is a very good round,,Sierra actually uses it to test their bullets with in a tunnel,,
there were several K98 actions,,if it is the Brno VZ24 it will handle just about anything,,some of the others can be suspect and would need checked out before I would buy it,,
if the stock looked good and it has an aftermarket trigger with a safety besides the one on the bolt and the bbl isnt pitted inside from long term storage it should be worth that kinda money,,if the bbl looks like it has hair growing out of the bore it is probably gonna have to be replaced and would effect $$
