Let's do the algebraic math:
Fusion > Core-Lokt in performance due to true bonded core. Core-Lokt's fail.
Fusion < Partitions in price and >= in performance
sum = Fusion 95gr (and Winchester Powermax) best whitetail bullet period
I've got stories, pictures of entry/exit wounds, and a few trophy deer to prove this equation
I think you've nailed it, but I think we could add -
Core-Lokt(plus a few other hunting bullets) = good enough for most deer
Up close, the bonded core should keep it from blowing up, especially when hitting bone.
