I am a reloader, I form cases, all of my dies have threads, threads on my dies make it possible to adjust my dies in my press to the shell holder, or, off the shell holder, or, below the shell holder as in the old proverbial 1/4 additional turn after contact.
Things that do not complicate my life, I do not have a Rock Chucker that cams over. If I did I could not use 'that press' with my Piggy Back attachments. My favorite cases? My favorite cases will not allow the bolt to close, meaning I have to adjust the die in the press to the shell holder when sizing the case. I have to know when to quit sizing.
I know, there is 'bump' and there is the magic .002", I will never understand how a reloader can bump a shoulder .002" but can not size a chase to fit the chamber, or worst, not know the length of the chamber.
Tools, I have 280 Remington cases, the 280 Remington case is .051" longer from the shoulder of the case to the case head than the length of a 30/06 case from the shoulder to the case head. How can I miss, .051"! There is no rule that requires me to fire the 280 case in the 30/06 chamber.
Then there is the parent 30/06 case that is longer from the shoulder to the case head. For me the case is a tool. My favorite cases are cases that are too long from the shoulder to the case head, that would be cases that will not allow the bolt to close. BECAUSE! ? If I chamber a round and the bolt closes I will not know by 'how much'.
