About to shoot shot from my smoothbore for the first time. I got hold of a little #6 shot so I can try it out. My quesion is what type of shot should be used in a smoothbore ---- steel, lead??? I wasn't sure what to use and didn't want to use anything that might harm the barrel. Also, not sure what this shot that I have is. Is there an easy way to tell if it is lead or steel or something? Probably won't be using shot very often, but want to give it a try on a clay bird or two to see how it goes. Thanks
