Giz, you answered in the precise fashion I was about to answer, having read the question. 168g is always a match bullet, to the best of my experience. If you target-shoot with 168g MatchKings (best of the best match target bullet), you would do well to standardize for hunting on the 165g GameKing hunting bullets. They have surprisingly good BC's, and were used to win long-range matches, like the Wimbledon Cup. The other brands (Nosler, Hornady, etc) also are great, but I've kinda stuck with Sierra. I'd have no problem with the MatchKings for pig, because I've resolved to shoot all my pigs behind the ear, from now on.

Will you, too, be one who stands in the gap?
