I shot a mule deer buck one time with my '06. I knocked him down and broke his back. I had one round left ( I had missed about 20 times before I saw this buck!) I was 16 at the time, peak of wrestling season and 10 feet tall and bullet-proof to boot. I grabbed the buck by the antlers to bulldog him down and he tossed me like I was a rag doll!
I jumped up and quickly used that last shot from my '06. That was my one lesson. I haven't tried that crap since!
