Just to start a whole new argument, I prefer the 150-grain bullets to the 165-grain bullets. My simple-minded reasoning is 1. There is just enough less recoil that the shooting is more comfortable. 2. Since 1950, my deer keep falling down, dead.
Were I hunting where deer field-dress notably above 150 pounds, I'd go the heavier bullets. If you don't handload, I'll agree on the Federal ammo.
