[QUOTE="Alex Wheeler, post: 1923045, member: 101859"] The OP is correct. A full length die is supposed to reduce the diameter of a case as well as set the shoulder back. Thats it's job. In most cases an off the shelf die will not reduce the diameter at the base above the extractor groove of a fired case from a saami minimum spec chamber, usually it will at the shoulder, often too much. Its a very well known issue among competitors and gunsmiths. Thats why we order resize reamers so we can make dies that actually work. The other option is increase the diameter of the chamber which is not ideal. With a die that works correctly, brass does not wear out. Its not supposed to be scrap in 5 firings. In Benchrest, 60-70k psi is normal, cases are full length sized every time, and you cant wear one out. I know of many that have reloaded cases over 100 times at high pressure. The key to long brass life is a well speced chamber, a full length die that works, and is used every time. I just bought a 300 PRC full length die for a wildcat Im going to do and the base of that die measures what the base of the chamber measures, in other words, guaranteed clickers. Ordered a resize reamer the next day. It is actually is big problem, and if more understood it and held the manufacturers accountable, we may get it fixed. [/QUOTE]
