Just run some Federal Heavyweight 7's through that thing and forget the TSS on that gun. Tight choke it on one side and you'll have at least at 45 yard gun but probably 50 if you find the right choke. Leave the other side more open and you'll be in business. Those Federal 7's are bad news.
I believe that the 1.25 oz hevi would be good to 50 yards; those SumToy chokes throw amazing patterns. Any shotgun I buy in the future will have one of his chokes made for it. They are built like a tank and shoot the best patterns I've seen.
