Great ammo - RIO Ammunition Royal Buck 20 ga 2 3/4in 9 plts Size 1 1345 fps

I have shot This from two 20-gauge shotguns, (Remington and Mossberg w 21" BBL's) with no problems at all. In fact I found it to be very consistent shooting ammo. I read a review recently where the writer questioned the quality of this ammo because it made a noise when they shook it, stated it was unsafe and could damage the gun. In my 49 years I have never Seen this as a problem.
I'm using them for home defense, and they hold a 2 1/2" group @ 7 yards and 9" @ 15 yards Mod choke.
