[QUOTE="Fiftydriver, post: 60286, member: 10"] Dirtybob1, When I fully accurize an action that will be rebarreled I always single point recut the threads. The reason is simply, this is the single best way to true the receiver threads so they are on the exact same axis as the receiver bolt way. Chasing the threads with a precision tap will clean up the threads but they will still be on teh original axial location as they were from trh factory, generally significantly off the axis of the botl way. Single point thread cutting is the best way I have found to true up receiver threads. When I am accurizing a rifle that the owner wants to use the factory barrel on, I will then simply chase the receiver threads with a precision 1.0625" tap(Rem 700) to clean up the threads and remove any burrs that may be present. This assures that when I fit the barrel I can "feel" how quality a fit I have with the barrel threads as I fit the barrel. Without this cleaning of the original threads, it is impossible to get an accurate idea of the thread fit you have machined. Again this is only when a factory barrel will be reused as you can not true the receiver threads without increasing their diameter and this would result in an even looser thread fit then is offered by the factory. For top results, single point thread cutting this the only way to do it. Good Shooting!!! Kirby Allen(50) [/QUOTE]
