What caliber are the rubber balls in the 40MM rubber ball munition for the Marines?

The United States Army has created a plethora of different types of 40 mm grenades in both the low-velocity 40×46mm and high-velocity 40×53mm calibers which uses what it calls a high-low propulsion system which keeps recoil forces within the boundaries of an infantry weapon. Presented on this page is a basic overview.

40×46mm LV (low velocity) is a NATO-standard high-low grenade launcher cartridge meant for hand-held grenade launchers such as the M79 M203 Milkor MGL Heckler & Koch AG36 and many more.. The propellant has low pressure and gives the projectile an average velocity of 78–84 m/s (256–276 ft/s) depending on the ammunition type.
