Utterly Mad

Once opon a time I was speculating on a Lahti 20mm, but then I saw one blow up. There's a bit of a design flaw in them that allows them to sometimes try to chamber two rounds at once, which results in the first round being detonated (for lack of a better word) by the second round as it pushes into the primer. That, plus the cost of shooting one, kinda turned me off them.
