Skip all of the trying different loads/chokes business. Go to www.indiancreekss.com, contact them and buy the blackdiamond strike choke tube they recommend for your gun. Then go to www.nitrocompany.co, contact them and order a box of H51013A 4X5X7 hevi shot. You will have the BEST choke/load combo for your gun, period. There is no better performance to be had. Welcome to the forums btw!
