Remove firing pin for cycle testing / OAL

[Bill_in_VA]

If you’re checking COAL of your reloads a set of dial calipers is both safer and far more accurate than cycling the cartridges through your gun. Another issue of concern to consider when cycling cartridges is setback - pushing the bullet deeper into the case mouth. While it won’t affect headspace (the 9mm headspaces on the case mouth), it can affect cartridge pressures as well as feeding reliability.
