Must have? Nice to have?
I must have a press, it is awkward without one, I do not need head space gages, comparators, COL to the ‘ojive’ gages, all are nice to have, not must have. The press, die and shell holder is as close to ‘must have’ there is.
Then there are transfers, standards and verifying, must know? Nice to know? If I can do ‘it’ with a standard and or transfer and if I can verify I do not need all the other tools, as must have, the other tools become nice to have.
