A Turkey Choke increases your chance of harvesting a turkey since a turkey choke produces a tighter group of pellets, which is specifically needed for turkey as opposed to a ducks or geese.
Typically, a turkey is 20-40 yards away, so a tighter group will help ensure those pellets do not end up ruining the meat. Duck and Geese chokes are meant to have a wider spread.
The most commonly used shotgun is the 12 Gauge Shotgun Choke Tubes. A 12 gauge shotgun offers ample power to take even the biggest game in America. The speed and power of a 12 gauge is very useful when taking Spring & Fall Turkeys as well.
You must have a turkey choke that is compatible with the gauge of your shotgun.
