Gene, if there is no corrosion around the primers that you can see, shoot them, and have fun. I shot a number of old roll crimped, purple 16 ga. paper shells with a Sears and Roebuck head stamp, while shooting clays with Nitrah Sunday afternoon, and they broke clays just fine. I don't hesitate to use them. There's just something that is just right about using vintage shells in vintage guns ............. and they kill doves and quail same as the new ones. Sometimes I have to cull paper shells because they have swollen too large to chamber. But again, if there is no corrosion evident around the primers I have found them to be mostly reliable, and lots of fun to use.
They smell good, too.
