I feel I am missing something obvious but I see case trimmers that rest on the shoulder to determine how much of the neck needs to be trimmed. It is touted as being more accurate than trimming from the OAL of the case.
Wouldn't the shoulder method require all shoulders to be the same requiring tighter tolerances when sizing or mixing sized and unsized cases? How can it be more accurate than just trimming off the OAL of the case?
Not trying to start a war here but just looking for info.
