asfar as terminal performance between the two I can't say one is better then the other Ive killed many deer and coyotes with core lokts and seen many deer and coyotes killed with power points. all I can say is both will do their job and thats kill whatever it hits. really theres is no difference between the two both are lead with a copper jacket the only factor that would play a roll on which one i would choose is which ever one gave the best accuracy in my rifle, in my case it was core lokts. both winchester and remington factory ammo asfar as clean burning propellents they are about the same and pretty clean but that federal classic ammo is about the dirtiest burning ammo ever I'v shot alot of different military surplus ammo that seemed cleaner then federal ammo.
