A friend of mine gave me a "Pattern Master" choke as a gift for my Remington 11-87 several years ago. Since the first time I took it out to the gun range I was impressed with it. At 50 yards I had roughly 50% more pellets in a 30 inch circle. Not only that but I have pulled off extended range shots ( 60-70 yards) on mallards, Maine Eiders, and geese that were just unreal using BBB & T shot. I also shot my first Gobbler last spring with it. At 40 yards the pattern is solid! Hope this helps.
