We have a major armadillo problem down on the farm. Holes all over the field. Dad had a cow come up lame recently, so we declared war. Anyway, back to the point, the 204 Ruger was the weapon of choice today. It is nasty! Blows them up. I shot one and we drove over to it. I asked my grandpa if it tore him up and he said it looked like you could stick your fist through it!!! The ammo was Remington Premier 32 grain Accutip. Advertised muzzle velocity of 4225 fps. The gun is a 24" fluted bull barrel AR.
