Welcome to OG and congratulations on your purchase of one of the best patterning guns for turkey hunting. I agree, you probably have the extra full turkey choke that came with the gun. Depending on what shell you decide to shoot, the .695 will probably give you fair results but the 835 seems to pattern it's best with a .670 to .675 choke. The people on this Forum have plenty of experience with patterning of the 835 and are willing to share their Knowledge with you. Good Luck setting up your 835 and Good Hunting.
