Never shot a bear, but have used Barnes X, XBT, XLC and TSX on small game to zebra. The smaller calibers will not make as big of a wound channel as the bigger rounds, and they tell me smile that bear have a layer of fat/hide/long hair that can soak up exit wound blood. For "big wound channels", its still hard to beat "Old School" round nose softpoints or soft spitzers. Partitons are the best of "both worlds". "if it were me" I would look for some 180gr round nose for the 30-06, barring that a 180/200 Partition. But that's just me...
