Shot a black bear with the 230 OTM (300 RUM, 3,000 fps muzzle, 120 yards) this week. Broadside shot, middle of the middle (but perhaps too far back). Bear dropped and rolled, then wobbled maybe 50 yards before expiring. The back part of the jacket was under the off-side skin. The core made a small exit wound. Gutless skinning, so can't say what happened inside. I hunt this bullet in grizzly country precisely to have the heaviest, highest-energy bullet my rifle will shoot, in case I need to stop a charging grizzly. Otherwise, I think a 168- or 180-grain Berger hunting bullet from my 280 AI would be a better choice for spring black bear.
