I know it when I see it, and it's based on how the firearm performs and the quality of the components rather than some arbitrary round count. I'll know long before 500 and most often after a few magazines or cylinders.

If a problem appears it gets addressed at the workbench, not the range. Or, I decide the guns not for me.


Forgive me my nonsense, as I also forgive the nonsense of those that think they talk sense.
