I would recommend going to a few forums to try to separate fan boy hype and real life results and data. 68forums.com is a wealth of knowledge on the 6.8 as well as other cartridges. I spend a fair amount of time there. If you can reload, the 6.8 spcII is the way to go if you are shooting out to 400 yds in my opinion. Beyond that there are better choices. Grendel bolts tend to break a little easier if you don't get a quality one. My next build is going to most likely be a Grendel though. I personally don't like the BO for hunting, shoving a larger bullet into an already small case leaving even less room for powder doesn't work in my mind. It does have it's place though. I took this deer at just over 200 yards this year with my 16" ARP 6.8spc. I have all the confidence that I can go out to 300 yards with factory ammo and still make an ethical kill. Beyond that is is more to do with my skills than the gun. Just a few of my random thoughts.
