I am tired of the "scoring or streaking", whichever term is correct, left on the inside of my Smith barrels after hunting or shooting at clays. I could be wrong, and please feel free to correct me if I am, but at the time these fine guns were made, weren't the shotshells paper with fiber wads and roll crimped? What I am after is, if you have a lead or source, on a manufacturer that offers a 12 ga. 2 1/2" shotshell with a fiber wad. The shell itself can be either plastic or paper. Low pressures would be nice also 5000 -7000 psi. Is there such a shotshell out there?
