Installing a redman barrel liner would allow you to take any left handed bolt action .22 lr rifle and convert it to .17 hm2. Cost $200 to $300 depending on your chosen gunsmith. May also be some .17 hm2 barrels available for switch barrel rifles. Post a thread on rimfire central under their .17 hm2 forum to see what responses you get. I'm a righty but I did convert bolt action rifle a few years ago.
