All depends on the ammo. If you match a bullet to your game or purpose, of course the Win Mag will beat out the 06. If you want penetration, pick a thick skinned bullet or armor type bullet. If you are shooting deer, pick a nosler or something. Believe it or not, I can pentrate more with my bow than you can with you 06. Does it make it a better performer? I think not. With the variety of bullets out there, you can meet about any purpose you got.
