I am shooting a 270 Weatherby for elk and my gun loves the accubonds. The only advantage of the partitions are their toughness and the fact that you can get a 160gr bullet. However, accuracy is more important to me, because if you can't hit em in the vitals, then it doesn't matter what bullet you have. The accubonds have that "ballistic" teflon tip on them and fly really well. With the right load, you should be zeroed at 200yds and about 3.5" low at 300.

Where in Idaho are you going?
