Wow, that is wicked cool! My little brass mortar shoots a bb about four feet with 2-3gr of Pyrodex and a firecracker fuse, knocks down little plastic toy soldiers and stinks the whole house up! I'd love to build a much bigger one some day. It would really piss off my obnoxious neighbors.
If I can see it, I can hit it. Now, where did I put my glasses?
