I have a winchester defender which will hold 8 rounds of ammo. I put a Advanced Technology top folding stock with the ammo holder on the folding arm to hold an extra 5 rounds. It also carries their heat shield. I use it as my primary grouse gun because I needed a gun with a short barrel because my land is heavily wooded with cedars and other trees. It also is fun to shoot with buckshot even though the 3inchers can start to really pound ya.
