Kindrox,
Go to the store or shop online. get a box each of the following -
Hornady Tap low/managed recoil 00 2 3/4", Remington managed recoil 00, Fiocchi managed recoil 00, and Federal low recoil 00. The Federal ammo can be confusing because they have 3 or 4 different lines of buckshot. Try to get the box that says LOW RECOIL and has the FLITEWAD technology logo on it. There's Federal Tactical, Vital-Shok and Power Shok. The first two can have the Flitewad but Power Shock doesnt, I don't believe. It's probably more than decent, but for my family's home I'd probably avoid it. If you can't find a Federal reduced load with Flitewad, I'd probably decide from the first three.
Take the 3 or 4 brands out and pattern at 15 yards (generally prescribed HD range). Bring enough tagrets and a camera and a sharpie to label each. I'd use at least 2-3 shots of each to make sure you don't get any fluke patterns
I'd go with the best out of that.
