It will work just fine, you just need to be about 10 yards closer than you would with a full choke. Get some good turkey loads with copper plated shot. I like # 5 shot Federal Premiums, but any of the Big Three are good. You might be better off with #6 shot for more pellet count at the closer range. Then get some turkey head and neck targets and start shooting. Back up five yards, shoot. Back up 5 yards, shoot. When you can't kill the paper turkey, you have gone too far. Now you know the gun and load's max range.
