Yep, they were called cap pistols.

Oh my! We were some naughty little freepers, weren't we?

I never did try doing a whole roll at once, for the mega-bang. I stuck to hitting the little spot accurately with a small hammer.

But then, I'm a female. ;)

I used to lay them out and hit them in succession as fast as I could with a hammer like you describe. There really was no comparison to the whole roll properly smashed with a maul. My ears start ringing just thinking about it.

Not naughty...possibly now hearing impaired, but not naughty.
