The proper way to give measurements is:
Diameter of case just below beginning of the shoulder
diameter of neck
diameter of bullet just above the case mouth (critical, and one you do not show on this thread)
Length of the neck from the top of the shoulder to the case mouth
Overall case length
Overall cartridge length
From your pictures, most of us realize that these measurements may be compromised by the terrible
condition of the cartridges, although in most instances, it will only be “one way” and that is to increase a
measurement due to the thick crust of corrosion on the cartridge.
Giving all these measurements would take away many of the guesses. The measures could be simply typed into the thread. I do not see the necessity of showing a picture of the caliper readings, which strikes me as more work and more space taken up for no gain.
Just my opinion.
