Went out yesterday afternoon to pattern some 3" Fed. TSS 9's I bought a few weeks back and all I can say is WOW! My Mossberg 500 with the factory full choke put out a great pattern at 40, I ran them thru my 835 w/ the Star Dot and they shot good thru that but it was a little tight at 40, going to try the factory Ulti-Full it came with to see how it does thru that. I even shot my old single shot Savage Stevens Model 940B with a full choke at 40 and it patterned nice thru that gun, never would have thought it would ever be a gun I could shoot out to 40. I've run Hevi 13 thru it before and it was never good past 30. I'm a believer!
