10mm is also .40'.

...Which I know because 10mm auto is the parent cartridge of .40S&W, which was just cut down to be shorter, but still uses the same projectiles.

Can I be that person???

AkShUaLlY An inch is not PrEcIsElY 2.5 cm but is /defined/ to be 2.54 ish cm so 0.4” is in ReAlItY 10.6 mm.

Ok im sorry. I’ll show myself out.
