CANNELLO (plural Cannelli). Accdg to Military Dictionary (AddnlRef A), it is not a Cannon Primer, but it is. rather a Projectile Primer.

Here primers and igniters are separate elements and not in one piece as for igniting proplnts in gun howitzer cannons, and in recoilless rifles. The weapons known as 60-mm Mortar Cannons M2 M19 arid 81-mm Mortar Cannons Ml M29 are smooth-bore. 

The purpose of a cartridge case(especially when used in recoil-type cannons) is not only to serve as a container for proplnt, primer and projectile, but also to prevent the escape of gas from die rear of weapon on firing the proplnt.
