For a real close range bear thumper, try the 220 gr. Nosler Partition at around 2400 fps. It will give you sufficient penetration and more. The 250's will probably work, but there is the chance they will not stabilize in your barrel, and hit the bear at an angle or sideways, and penetrate very little. To be realistic, any 165 gr. premium bullet on up through the 180's and 200 gr. bullets will work very well on a black bear. You don't need the high speed for a close shot over bait, so a 200 gr. load makes sense, as does the 220 gr. weight. Accuracy will be really a non factor for shooting at close range, so almost any load will work. My choice would be a 165 gr. Barnes X, as they are superb killers, and penetrate like a bullet weighing 200 gr., like a Partition, Grand Slam, etc. I never really understood the need for a 250 gr. bullet in a 30 cal., and it makes less sense now than ever, with the super bullets like X's & Fail Safes.
