I have shot three armadillos in my front yard late at night. Where ilive is what I call semi country. i am using a 410 due to houses close by. The first I shot with buck shot in a 3 in Shelly pellet load the second i yugo with no4 shot also a 3 in shell. The last I shot with a different type of buck shot load they used small disk the first and last armadillo ran after I hit them making me question my load. The second I hit about 8 feet away and it rolled and jumped but it too still ran off. What can I use that would be better with houses close by.
