+1 for the Partitions. They can be a bit finicky to get to shoot dimes but there is no question they do an exceptionally good job of knocking stuff down. I shoot 150's in my .280 and I know many, many guys using 150's in their .270's for moose. These are happy guys! I have no experience with Accubonds, so can't comment at all.
I tend to stay away from the Barnes, as i think they're almost too tough. While I haven't lost any animals because of the small(ish) holes they produce, I prefer something that upsets a bit more. Just personal preference is all. However, if I were way up north where there are big brown guys that could make a mess of me, I don't know that I would go with anything else.
In recent years, I have been trying Hornady Interbonds and GMX's. Kinda partial to Hornady. Accuracy wise, I'm very happy with these bullets in .300 WM, .300WSM, .308, & .280 (don't own all these, just load & test lots for friends). In my personal experience and feedback from friends, terminal performance has been pretty darn good on moose, elk, and mule & whitetail deer. I can't believe the prices of the Interbonds now, though.
Tough to go wrong with the Partitions unless your gun really doesn't like them.
