You can do a lot with the cartridge. Skeet range I use 3/4 oz in my 26 inch 12 G Parker. Small bird hunting 7/8 oz. Shell going in the chamber is 12. Recoil and pattern on paper you can't tell it from a 28 or 20. Buy a whole,lot of RST's for what tubes cost.

You ought to go to the Southern SxS end October Georgetown SC RST will,probably be there as well,as the chance to see more Churchill's thousands of fine SxS's
