Hi Dom, well, I don’t have any experience with an animal that size, but I’ll try to stir the pot here to get you some more qualified responses. I think with the 300 up front you would be safe. I read that it might be on the bottom end of good, but folks hunted those deer with less foc. What’s fhe total weight of the arrow you plan to build?
I believe the proper order of things for penetration is something like this; straight arrow flight, sharp blades, weight of arrow and then increased foc. Of course, accuracy should have been the first thing. Let us know how you make out. Best dwc
