Before I knew better, I killed a deer with an M-1 with out giving much thought about selecting ammunition. I used 150 grain Remington Core-Lokt in 30 - 06. I have since learned to be more discerning about what to feed my M-1's. My question, is there a recommended factory ammo suitable for deer hunting with chamber pressures and burn rates that closely duplicate military loads, making it suitable M1 fodder?
