[QUOTE="CONatureBoy, post: 2820263, member: 118769"] This weekend I shot a nine-year-old black bear at 120 yards with a .30-caliber Berger 230-grain OTM (300 RUM, 3,000 fps at the muzzle). Broadside, "middle of the middle" exactly (which was a bit farther aft than I intended). The entrance wound and exit wound both were bullet-diameter holes. The guide found the back third or so of the jacket just inside the skin at the exit wound. Some or all of the lead core must have created the exit wound, and the rest of the jacket must have fragmented between entrance and exit. The guide did gutless field dressing, and we didn't post-mortem after skinning the carcass, so I can't say what the effects were in the boiler room. The bear fell when shot, rolled downhill about 30 yards, and wobbled away over the crest of a sidehill. It was near dusk (and cold) in high-altitude grizzly country (NW Wyoming), so we left the bear 'till the next morning. I found it about 50 yards from where it stood after rolling downhill. I conclude the bullet performed well enough. It was likely too much bullet for a spring black bear at close range (spring bears have no fat left under the skin to help a bullet open up before reaching the vitals). And better bullet placement (or a more frangible bullet) might have made a difference. I would have hunted a lighter bullet, had I not been in grizzly country.
