The manual states a TLL of 2.539", but I have been using 2.448" I did not find a good discussion on this when I searched, so I was curious as to anyone else's experience with TTL that is supposedly too short. Any problems, issues, or unexpected results? Steve on the Nosler board states, based on good documentation, that we can go .020 under case length and it is still in spec. What is the preferred method for TTL: Lathe or Trim die? Do the lathe guys have a hard metal case of correct TTL so that the cutter does not not accidently alter the case length?
