Gray, Sako `s have a very good resale if not modified. To go to a .22-250 you would also need some bolt work for the larger case, even if it was long enough. If the rifle shoots good I would not even consider modifing it. The .222 mag. is a great round, if you reload, but loaded ammo is getting hard to find. I have several custom guns, but would never mess with a good Sako. If your looking for an easy action for a custom gun get a Savage, you can change barrels yourself, if you know how to set head space. Just my oppenion.
