you want power? my friend works at Lafarge cement, the biggest cement co in the world. when they get scale build up in the giant kilns , they use an 8 GAUGE 4" MAGNUM SOLID COPPER SLUG to shoot it out. You should see this cannon!! They bolt it to the floor and blast away INSIDE THE KILN! PSYCHOS! I mean, you could stop a Sherman Tank with this thing!!!
Moose, I've seen an eight ga before. I think it was on TK & Mike's duck hunting or turkey hunting.
No seriously, most states don't allow anything bigger than a 10ga and the 8ga would be about at effective as a .50cal. I personally like to make my burger after I skin the deer.
