			Evan, you cannot rebarrel a Ruger 10/22 to 17 HM2.  It is fine to rebarrel a FIXED breech gun, but not a semi-auto of any kind.   
 
The pressure and recoil spike is much, much higher with either of the little 17 rimfires. It requires a new, very massive bolt and extra strength springs in addition to the barrel.
