armadillos are everywhere on my property... a .22 seems underpowered unless for the infamous headshot. I shot a dillo earlier this year with my .22, and it took three vitals shots to bring him down, and another to finish him off. I'd prefer the'ol .223; easy to bring close up as well as long ranges. I wish I had a picture of the dillo I took, but the winchester 45gr. JHP varmint rounds are NASTY. One shot from about 12 yds. put a fist-sized entry hole in him and strung his vitals out. 'nuff said.
