P.S. - The medical profession doesn't have eyeball transplants perfected yet!
Always wear safety glasses when working around primers or with any other reloading activity.
In the first place, I always have eye protection...as I wear glasses instead of contacts now.
Secondly...sensitive hand grenade?? Sensitive noise-maker, maybe.
Thirdly, I've unseated primers for a couple different reasons and there is no reason to toss the case out just because you have a bad primer or seated it wrong.
