LEGAL CAUTION: Whenever you use a modified weapon or unusual ammunition you will be subject to the bad guys lawyer trying to prove malicious intent even in self defense. IE: flechettes. Your much better off having used OO buck if you find yourself in front of a jury or DA. Besides OO buck will always get the job done. It's the prefered round of LEO's everywhere.
Case you site a case where a guy was found guilty on a legit shooting based off of this? Ayoob likes to talk about this a lot but I have never actually heard of a case where it influenced the jury.
Right, but I'm thinking worst case scenario here.
Suppose you had been a lone policeman on duty the day the Muslims stormed Beslan Middle School #1, and all you had was your duty-issue 12 gauge, and it was you against 15-20 Muslims, at fairly close range.
What would you want as your ammunition?
