Why not just go buy a 10/22 Mag rifle???, Then you can convert it to a .17HMR...
Old T. is right on the nose 10/22 can not be converted to 22mag for reasons he stated.
Good luck finding a 10 / 22 mag for sale and if you do ya better hope the feller is as dumb as a bucket of hair and have no idea what they are worth since they are not made any more.
Me lucky I have one and love it.
