Could you potentially ignite a primer by gently closing the bolt on it with the trigger pulled so the pin presses into the back of it?

About squashes them in half and they didn't go off.
As a general comment it's fair to say they are pretty safe, stable.
Never say never though... They are an explosive after all, and you'd hate to have one go off while doing something foolish.
inervate wrote:Yup, that's pretty squashed.
Good to see they're tough to accidentally set off.

I know the videos Seconds is talking about though, and there is definitely enough 'pop' in the primer to send some burning gas/debris into your eyes.
