I'm with BHW, 6.8 is bad ass! I have two complete rifles and two more uppers in it and a Dillion 550B dedicated to loading it. We have killed a load of hogs and coyotes on my Dad's property with those guns. 110 HDY AMAX or Barnes 110 TSX is a death dealer. I like to think of it as the .40 S&W of the carbine world. It's not a .308 but if you want something light, portable and deadly it will do the job. I have shot past 500 with it but it starts to lose a bit of steam out there. Inside of 500, if you can see you can smoke it.
