for me, the 06' (and 308win) shooting 180gr partitions works perfectly. of the 3 the op mentioned, i'd go with the accubond. if willing to try other brands, i'd suggest factory loaded hornady interbonds or fed premium 180gr partitions. while some are confident taking longer shots, i can't remember shooting an elk past around 325yds, and the vast majority have been under 200. ymmv.
