I know this is an older post but for those doing searches on 55gr Gamekings I thought I'd add some first hand experience. I've been using 55gr Gamekings out of a 22-250 for Antelope and Deer for MANY years (Dozens of animals). I have never had one get away. I've shot speedgoats out to 480 yards with clean kills. Always performs great. And it's one of my most accurate loads. Out of my Savage BVSS I get 1/2" groups at 200 yards (1/4 MOA).
Don't listen to the people who say you need a 300 win mag for goats/deer. You put a hole in the right spot and it's going to go down. And no... you shouldn't rely on a bigger caliber to fix your mistakes. That just makes you sloppy.
