[Eppie]

I can think of lots of destructive hobbies, bungie jumping, base jumping, snowboarding, cliff diving, etc... But making your own primers tops them all.

With the others persuits it only involves personal destruction. But by making primers at home you would be putting your family and your home at risk. That seems like the apex of irresponsability. Unless your trying to teach home grown terrorist on how to make high explosives.
