Bill, let us know how it shoots for you. I am waiting on delivery of the new Tikka t1x in 22lr. Should be here (hopefully) in the next 6-8 weeks. I will probably go your route for one of my 455's and get a 17HMR barrel for it. Can't decide on varmint contour or trainer with the tangent sights. My 3 455's are all trainers and all good shooters. Fedderson makes a 22lr for the 455 but haven't come out with an 17HMR yet or I would have one of their barrels already. So many toys, so little cash or time.
