In SXS shotguns they don't always extract like plastic does, with a sharp backwards motion and when you or someone like a range officer steps on one and crushes an empty , it is an expensive incident. They do look cool though. You don't need any presses to reload them, just a pin punch to deprime, a piece of dowel and a flat surface to prime, pour in right amount of powder, dowel to press in wads, pour in right amount of shot , place thin cardboard wad over shot , seal with waterglass or white glue. If you use black powder , throw your brass into a can or jar of soapy water and clean when you get home ,if you don't the BP salts will start to eat the case. Sometimes you will have to lube and resize the brass, I used an old Lee press that has a loose sizing ring that I forced on with a piece of pipe then forced off with the press. You can't use the press to size unless they have regular shotgun primers, some do ,some don't. Also watch what you buy because some brass cases have berdan primers and they are not as easy to use or get. I have used old brass cases I have bought at gun shows but some of them had different sized primers also, they were not large rifle and they were not shotgun. ??
