LOL yeah, that Bugs Bunny episode sums it up pretty well. "These blockbuster bombs don't blow up unless you hit them just right."

It's all just an amusing story now and I actually got a good laugh reading all the responses and personal anecdotes. I guess nobody is immune to at least an occasional lapse of judgement.

Technically, the situation may not have been THAT critical. I don't know much about Baratol but TNT is very insensitive to shock and friction and basically a pain to detonate. I think it only ignites at something like 780°F if my old manual was right. Of course, that does not make me any less of an idiot!

The bottom line is, I'm really mad at myself. I should've known better. I've always been very careful around firearms and explosives but this time, I made a big mistake. I assumed the grenade was empty and I assumed the previous owner had made sure it was deactivated. Never again!
