I have a 20 ga. Tulle that's saying to me, every time I look at her, "take me turkey hunting, take me turkey hunting." I've shot it a fair amount with balls, and plinked enough with shot loads to know the basics--anyone have any advice as to a starting load for turkeys? I realize a 12 ga would be better for hunting goblers, but the Tulle is what I have and season opens in a week. Thanks for any help.
