Does anyone know where I might be able to obtain ammo for this gun? I have about 200 rounds now but I'm not shooting them because nobody around here seems to know much about this gun. I have heard that for a box of 50 rounds it can cost up to $80(apparently its pretty rare). The gun is in great shape, looks like it never was shot. I'm thinking ths might be on of those guns that I dont shoot anymore and to just keep it nice and pretty?
