Fired with safety cap

Hello,

We often find unexploded shells fired with safety device.

I suppose that gunners had to take infernal cadences.

(picture 1 : fired 18Pr HE fuze No106 with safety cap - picture 2 : fired 4.5in Gas fuze No44 with safety cap)

Not sure if applicable with these fuzes - but I do recall being told that safety caps were sometimes left on on percussion fuzes in order to act as a delay to alow `penetration` into the object struck?
I think this was discussed with regards to No117/119 type fuzes etc.
The idea being that the safety cap would collapse/disintegrate on impact still allowing the percussion action to be fired but the slight delay caused by the cap having to break up would allow the projectile to `enter` the objest struck.
Revetments etc?
