I was out shooting clay with some friends yesterday. 150 rounds of 12Ga + 25 rounds of 3" 00-buck and 10 rounds of 2.75" slug (per person, there were three of us).... Many pigeons, watermelon, cantaloupe, and dirt clods were destroyed yesterday. My shoulder is so sore today! I have to say... 00-buck is one of my favorite defense rounds... forget the 9mm vs. .45 debate --- 12ga 00-buck wins! Too bad you can't conceal carry a shotgun Edit: Took some video of the carnage with my iPhone - but sadly it isn't 100% PG rated (due to language from others in the group) and I don't have any advanced video editing software to bleep things out... So I won't post it up here.
