That's a very light load, some may hunt with #7, but I use something a bit heavier. More importantly, its a game & target load, which is also a lighter load, and it's steel shot, which retains less energy down range because compared to #7 lead since steel isn't as dense. So if it was #7, lead, 3" mag., I'd say go for it, though I'd personally still look at #5 or #6, but I would not go with what you got there. A turkey is a big, tough bird.
