Match bullets are all I use- shot placement is the key to clean kills. I have taken evrything in the US with a 308 and 175 MK- prairie dogs, badgers, coyotes, deer, antelope, bear, hogs, exotics, and even the mighty bison.
This site was started by guys who made longrange kills with match bullets!!!! That was what this site was and still is about.....
So if the 168 shoots the best (I would try the 175s) by all means USE them.....and enjoy the barbeque!!!!! And 223 with 77gr, 338 Lapua, 6.5 WSM, 6.5-284 both with 142s, 7mm with 168s- now 175s, and 243 with 107s.......
