Iíve been searching for the ďrealĒ actual dimensions and tolerances for a 45 ACP FMJ bullet and casing. Everything Iíve found on the net either leaves off some dimensions, lacks the appropriate dimension tolerances, or is in conflict with other information Iíve already found. Iím starting to think that (1) the manufactures do not want to share this information or (2) no two rounds by different manufactures are actually the same. Which might explain a lot of other ongoing issues we have all seen or heard about. In any case if you know where the ďRealĒ definitive information can be found I would appreciate it. Iíve even done a search in the patent history with little success.
