There's no "fancy" Turkey Loads for the 16 gauge
so just look at the 1-1/8 and 1-1/4 oz loads
they should go around 1300 fps (thats what "standard" Turkey loads go) Last year one of my buddies shot a turkey with Federal Wing-Shok #6's,16 gauge
look for
Remington express
Federal Wing-shok,Game-Shok
Winchester High brass
They all will work i shot a few turkeys with some federal #4's 1-1/4 oz 12 gauge
