The so-called "Mythbusters" and I don't always see eye-to-eye. But they sure are fun. They blow stuff up, shoot things, and sometimes even get stabby-stabby. Take this video in which they try various machine guns to chop down a tree. It's good to know if these things can work in my line of work. They weren't able to make it work until they turned to the GE 7.62mm Minigun. Imagine, if you can, spitting 50 rounds per second at an on-coming horde of zombies. Something like this can put the hurt on creatures that otherwise are unaffected by mundane weapons; 50 rounds per second dumps tremendous energy into a body and can overtax even a healing factor.
