They are not really that easy to find anymore. The 22-250 is kind of a dead round with the newer crowd of shooters and the "black" guns in 223/556. That's why I jumped on this one when I found the deal. I'm currently checking on prices to have it turned/threaded and that cost may be the deciding factor in the project. I have done machine work with lathes and mills but sadly no longer have access to any machines and cutting threads was something I never tried.It’s likely easier to just sell that barrel in the classifieds and pick up another barrel that’s already a small shank.
