The size and type of turkey load you use is really a personal preference. The main shell sizes are 2 ¾, 3 and 3 ½ inches and the size you use depends on the gun gauge. Lead pellets are the most popular and are available with copper-plating. Tungsten is a new option for turkey loads. It is a heavier medal with the weight to make it go further. This gives the option of more, smaller pellets going to your target. It’s a personal preference that is best determined by trial and error. Just get out there and shoot a variety of loads with different chokes.
