Does anyone have any terminal performance experience using the 65 grain Sierra GameKing? I am wondering how it would stack up against the various open tip match bullets recommended.

The search function returns lots of hits for Sierra, but I am not finding any data for the 65 gr. GameKing. I have yet to fire it in an AR platform, but in a bolt action 1/9 twist Winchester 70 heavy barrel it can turn in .5 to .6 inch five round groups at 100 yards.
