...much like the local cadet corps who are (were anyway, don't know that they have firearms anymore) taught to cock and snap the C.No7 repeatedly onto an empty chamber to demonstrate that they are empty... It took a lot of cringing, begging, cajoling and crying to convince the staff instructors to modify their drill...
In the "civilian world" where people have to repair their own (or borrowed) property, the first thing anyone who deals with rimfire is taught in my experience is how potentially damaging an inertial firing pin is to a rimfire chamber...
Foolishly perhaps, I had previously wondered how anything could mechanically go wrong with a C.No7 which would force the unit to send the rifle back for cannibalization and conversion to deactivated status...
