Patterning a turkey load is pretty simple. Set up paper targets at varying ranges and see how the load performs at each range. I personally like to shoot at 10 to 20-yard increments out to roughly 60 yards. It's best to use targets with the silhouette of a turkey’s head and neck so you have an idea of how many pellets land in the kill zone. If you’re testing out multiple loads, use fresh targets for each range and count how many pellets are on paper, how many are in the kill zone, and measure roughly how tight the pattern is. Note flyers, strange tears from deformed pellets, and if there are large gaps in the pattern. You may want to try different choke tubes as well to see how that affects the pattern at each range. Then simply pick the best performing load and choke combination for your needs.
