I waterfowl exclusively with a later production Field Grade. I shoot Classic doubles when I run out of ITX handloads. I tend to shoot 4, 5, or 6 shot over decoys and pass shooting. After close to 500 hand loads and around 250 or so rounds of classic doubles, I've seen no damage. The stock is glassed, but the gun is otherwise original. My gun patterns really nice with the #6 Classic Doubles. Choked modified and full. Just my comments, though. It's your gun afterall.
