Here in Mid-Missouri we are starting to get a lot of land damage and erosion started by Armadillos digging holes all over the fields and woods, and my wife's gardens. Occasionally I see them out digging just as its getting dark, but still light enough to shoot at them. I have only shot at a couple so far, but wondered what is needed to kill them? Are they a super hard shell that bullets bounce off of? Will a 223 that I use for ground hogs kill them easily? Or should I get out a 30 caliber with a 180 grain gas checked bullet?
