TSS #9 is very lethal and effective. It’s designed to kill at distance and maximize the number of pellets that will hit the vitals of a turkeys head/neck. Ultimately, it comes down to what you prefer as a caller and hunter. A good medium to consider are Hevi-Shot loads. They are typically a blend of different metals and pellet sizes. I have killed birds anywhere from 4 yards out to 62 yards with these shells. They pattern great and minimize the risk of having a pattern that’s too tight like you’re mentioning.
