Like Larry said, Estates are probably the way to go, except you can't reload them. Or at least I wouldn't trust them to be reloaded. 25 lbs. of shot makes about two flats of 1 1/8 oz. of my loads, give or take, so if you are a reloader just shoot sparingly. If you are a hunter, a flat of shells should just about last you all year. Gun Clubs are excellent, too, but they won't eject in most Ljutic trap guns so I can't use them in mine. I could always shoot my Beretta I guess, but it's just not the same. So I just shoot occasionally.
