RE: 125 grain 4 blade stingers?
I haven't hunted turkeys (yet), so take this for what it's worth. With the poundage you are pulling, I'd go with the one that flies the best and cuts the biggest hole. Penetration won't be a problem, or broadhead durability as far as that goes. A Bodkin will most likely do as well or better that an expensive head on the birds, especilly if you take a head shot. Not knocking Magnus at all, they are great, but the turkey birds shouldn't require the very best to get the job done.
