Silvers: Stay with AH Fox. For a vintage sporting clays gun that you intend to shoot a lot find a nice AE with 30 or 32 inch barrels. Many of the longer barreled guns were # 2 or #3 weight. The gun should weight around 7 3/4 to 8lbs. Find a gun that has good condition but has little collector value/interest because it has had some restoration. Have a good stock man go over the wood to make sure it is sound and repair the head area as or if needed. Have the stock bent (the straight gain of an A should bend easily). Add LOP with a recoil pad. Have the chambers lenghtened, chokes modified. A #2 frame Parker VH would also be an excellent choice.
