If you have a variation for .22lr then you can buy either bolt. semi, straightpull,or lever action. The variation is for the calibre not the action.
The sako will be a quality item out of the box, the 10/22 may or may not take a serious amount of work to get it to do what you want. Bearing in mind a fully sorted custom 10/22 could cost in excess of £800 and all you may have left of the existing rifle is the mag.
