and me each a barrel for our Contenders. All the same day, same reamer, 2 from the same barrel blank the 3rd from a different. Barrel blank made by the same company. When loading once fired ammo, none of the 3 will interchange ammo. The loaded rounds will almost chamber in the other guns but not quite. I had to use Magic Markers to color the base of each round different colors so we could keep them separated.

A couple of years before that Kase and Colleen were both into combat shooting. We built 2 identical 38 Supers, both on Springfield Armory guns, same barrel companies, same everything, but again the ammo shot in one would not chamber in the other when reloaded. And all ammo was loaded on the same Dillon 450 press, and all at the same sitting.
