I have a Mossberg 500 "riot gun" that I inherited from my dad. It has some type of rough coating on it I think to protect it from the elements, as Dad had it on a boat. Anyway, I took it to the range a while back with some low recoil 00 buck (12ga), and some standard field loads with #8 shot. The low recoil loads we fairly pleasant to shoot, but the field loads were brutal. I could not believe the difference in the recoil. I keep it loaded with the low recoil buck. But,wow, at 7 yards, either load shredded the target. I apologized to the attendant for the mess I made, but it was fun.
