I bought a case of #2's and #3's. The load is only 1 1/8 oz ( cost saving on shot). This results ( I believe) in a slightly caved in crimp. No opportunity to use on real birds yet but I have shot clays with the shells. VERY hot loads with a loud BOOM when they fire. They did stick in the chamber of my Model 12 Heavy duck but my 1100 ran great on them. My buddy had good luck in his old browning auto 5 and his sisters 1187 Remington. They are a decent shell but I would not buy them again no reason but I prefer Challenger steel and the price is comparable. I have no pattern opinions for you but at 1550 fps I bet they are average at best. Dissected the Score ammo has very round and consistent shot and a Guliandi wad, premium components in my opinion.
