Bob,
I bought a W&S a previous owner had opened up to just over CYL/CLY--.004 on both barrels. I use felt wad loads for grouse/ptarmigan, plastic shot cup loads for prairie grouse/preserve pheasants with excellent results. 7/8 or 1 oz. of #7's at 1150 does the job for me. Justin has a point about removing metal.....there is no turning back, but I tend to agree with Joe. I buy my guns to shoot, not just stick in the safe.
