I came across an FN Tachtical rifle chambered in 220swift. It has the synthetic bench type stock and heavy barrel with 1in15 twist and a Weaver 4x12 scope w/std ret. My questions are what is it worth roughly? If the throat is shot can it be rechambered to something else and what? If I had to re-barreled it, what would be my options with that action be? The gun looks to be in excellent condition on the outside... I will likely go back check it out some more as i didn't have time that day. Thanks for your comments.
