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!!!

I will see if i can get some pics, you'll enjoy them!

I think using that for deer hunting would end all controversy about shot placement, and, you probably wouldnt need to gut it afterwards....
