Most basic .22 rifles have their barrels pressed in and secured with a pin or set screw. Once the pin is removed, the barrel is clamped in a padded vise and the receiver carefully tapped backward and off. Age and rust can make this difficult.
I know nothing about Cooeys - a new barrel in .17HM2 would likely need it's chamber end machined to fit the receiver. Easy enough for a good gunsmith or talented hobbiest with a lathe.
