Great pattern, especially if you don't have a choke - Hornady Critical Defense 12 Gauge 8 Pellet 2.75 in Buckshot Shotgun Ammunition

I found this functions the absolute BEST after trying several premium 00 buck for my 870 Police Magnum which does not allow for configurable chokes. I can get (no joke) about 2-3" patterns from 10-15 yards- which I almost didn't believe when I first tried them. General rule is you get 1" of spread in your pattern per yard, so this far exceeded that standard. Other cheaper stuff I've run would get up to 12" patterns at this distance, so I was looking for something that would pattern under 6" without switching my barrel.

If you want super tight groups from a combat barrel, this is the stuff and worth the premium you pay.
