I have used 165 grain Sierra Gamekings on 7 Maine deer, including a 234 pound 8 pointer and a 175 pound 10. They are no where near as accurate in my Sako as plain jane 150 grain core-lokts but they have killed every deer I shot at. Actually not one of them even twitched after being shot. The last deer I shot was about 20 feet away and the exit wound was impressive to say the least.

That being said, I have had just as good luck with the core-lokts and will be going back to them this year.
