Yup we can't tell you whats best for you, only you and your shotgun can determine that.
All Turkey loads are good loads but don't perform the same way in each shotgun.

Do you have any friends that Hunt for Turkey? maybe they'd be willing to give you a few rounds
for you to try in your shotgun otherwise you'll have to buy and try different loads.
Try to start with the #6 shot, that's my only advice. and don't think a 2-3/4" load is too small.
A 2-3/4" round does just as good for me as a 3" or 3-1/2" but doesn't Thump the shoulder as bad.
Remington has a nice Turkey Target for downloading and printing <-Click to get the Target

Good Luck
