Topic Creep: Found this 9mm Luger ammo vs 9mm

[DonVoigt]

Let's just stretch the arbitrary +/- 0.001 to +/-0.002, to be more inclusive and recognize that nominal 9mm or .355 or .357 bullets will work just fine in any of them, and keep the Makarov too, 'cause .363 is close enough for Russian work.

Of course someone with the time could digress and discuss the potential range of maximum and minimum bore/land diameters and what to do about Metford or polygonal rifling measurement; then, add to that the practical or observed range of bulk manufactured nominal 9mm bullets themselves.

This thread could go on forever and not reach any conclusion, just more parameters to measure and questions.
