Using a Cup for Bullet Mic Practice

Most bullet mics are between 2-1/4" and 2-1/2" in diameter (the round holes in harp cases are 2-1/2"). Many of the cups and glasses in your house are this diameter, including standard 16oz water bottles. If you're new to playing a bullet mic, time spent with it in your hands is needed to gain a comfort level. You can of course play with the mic plugged into your amp, or unplugged (with cable disconnected if it's detachable) or even a household cup to create a mic analog. Either way, you're getting used to having that bullet shape be part of your harmonica hold.
