sharps4590,
Yes of course 9.3x72R is a very common old drilling cartridge - maybe the most common of them all. But the question was about Nitro rounds so I eliminated cartridges that originated as black powder rounds.
I should probably also mention the most common drilling smoothbore chamberings. These are 16/65 for prewar guns and 16/70 for the postwar period.

With kind regards,
Jani
