Mythbusters did a decent job on this one, but it doesn't take a genius to realize without a barrel there's no real speed being generated, it can't really get going very fast.

A few years ago, I was awakened at about 2am by what I thought was a string of firecrackers set off by some asshole.

When it kept going on and on, I got op to go see who the asshole was.

It turned out, the house behind the house across the street from us was on fire. The homeowner had more that 1200 rounds of ammo, for some reason.

I'd still rather go to a chili cook-off.

when I was a kid we used to burn leaves in a 55 gallon drum, and my granddad showed me that you could throw an entire 22lr round into the drum and it would pop like a firecracker and shoot a plume of ashes/embers straight up like 20 feet
