I can tell you from personal experience that a 17 Remington H&R will give you nothing but grief. It is an extremely high pressure round, about 10,000psi higher than a 17 FB, it will stick cases no matter what you do to the chamber and the one I had showed poor accuracy. The 17 FB is a totally different story in the Handi, I cannot tell you why, sort of like the grief many people have with the 243 Handi's, some rounds just aren't a good fit I guess. Every FB I have built was a great shooter, whether it was a rechamber of a H&R barrel or a stub job. Good luck, let us know what you make out of it. Larry
