[QUOTE="JBM, post: 34064, member: 1969"] Harold Vaughn's book, "Rifle Accuracy Facts" , has an entire chapter on "Barrel-Receiver Threaded Joint Motion" (starts on page 103). He shows that a barrel that is not torqued property will move slightly. He also shows examples a couple of different kinds of threads, e.g. the Spiralock Ramp Thread", to ensure that all threads are equally loaded (due to stretching of the threaded portion of the barrel). He tests this new thread with a barrel torqued to 200 ft-lbs using teflon tape as a lubricant and it eliminated flyers on his rifle. The book is available from Precision Shooting, (860) 645-8776.
