Centurion 12 gauge 2 inch "00" buckshot ammo (10 rds)
Hey guys: it looks like Ammunition To Go is only stocking the 2 3/4 Centurion stuff right now, but I think that is where I got it at least 1 year ago or more.
The link above looks to be a current source in addition to the CTD link posted.
Keep in mind that there are several sizes of buckshot.
There are 2 inch shells that fire 6, 9 or 12 pieces of shot I think.
I would not wish to receive 9ea. - .30 caliber projectiles into my person.
Have fun shopping around.
