I have never heard of a GK penciling through anything , particularly at 2900 fps,but I have heard a lot about Barnes bullets doing that and even partitions, but I suppose it could happen.
Had it happen to me with a 180 grain .308 GameKing. Took a shot to finish off a hunting partner's crippled doe, broken front leg, at 425 yards as best I could pace it off under the conditions. Between the ribs in, through both lungs, and between the ribs out. Of course it ran so a farmhouse was directly behind it from where I stood. Died in the trees behind the farmhouse about a quarter mile away.
But then I've seen the same thing happen with a .243 at less than 100 yards. (Uncle Jack just about threw the new rifle he was bragging up into a ditch.
) Not surprising as lungs are mostly just more air. Weird things do happen from time to time if you hunt long enough though I seem to get more than my share.
