Definitely still a use,
particularly in MOUT. Not so much on the Afghan planes, but they were pretty useful in Somalia. Watched my Top butt stroke the heck outta a Somali who was trying to steal his Berretta. Should see how big the guys eyes got when he looked up at the business end of the 12 ga. Like something outta a cartoon.
I have a friend who used to be PD, and he tells me he went through some crazy ricochet training where they were taught to "bounce" buckshot around corners to help take a hallway. Something you can't do so much with a M4. Didn't actually see it myself so don't blast me if it's BS, but I've known the guy for abt 6 yrs & he's not known to be a BS'er.
There was another good article this past sumemr abt tricking out a Rem 870, I recallthem saying it was very useful taking a ship. Guess the steel hallways would ricochet really well, sans hostages of course....
Every tool box has more than one tool, every gun safe should have a good shotgun.
