I purchased a Remington 870 Super Mag Turkey Shotgun at Bass Pro Shop a couple of weeks ago. I've taken it out for some patterning and at 40 yards that pattern is large. I'm new to this so bear with me, but are there higher quality turkey hunting choke tubes than the one that came with the gun that will give me a tighter pattern, or are they all the turkey hunting choke tubes basicly the same?
