A .270 might work, but my opinion is that anything under a .30 caliber bullet and you are pi$$ing in the wind. 100% agree that .308 is the minimum for black bears. .30-06 is better. It doesn't make sense to be undergunned for something that could possibly take you out if the initial shot was not as good as it needed to be.
Might? A 270's more than adequate and is far from pi$$ing in the wind. BB's aren't all that hard to kill as long as you choose the right bullet and place it where it needs to go.
Whoa ... I don't think Jim was trying to belittle your .270 which is a very hot sub .30 cal. cartridge. This thread was about whether a .243 was an unethical cartridge to use because, in an average shot placement, it might be somewhat less humane.
Everyone talks about "as long as you place the shot in the right place" ... as if you're going to find that bear standing still (profile) out in the open ... as if you're at the shooting range.
I come across many BB's, both bear hunting & not, & have never seen one presenting itself "that way." They are almost always moving or partially behind a tree or thru 30 to 70 yards of brush.
Hence, we take the best shot we can, if at all. Thus, most of us feel taking that shot with a lite bullet not much bigger than a .22, is probably somewhat unethical.
Look, in WWII we found .50 bullets did a nice job shooting down enemy planes. But a 20mm or 30mm nose cannon did it better, taking fewer shots because it made bigger holes.
Your .270 is good, a bronze tip 30-06 is probably better ... but the point here was ... a .243 is definitely on the lite side to be used as a bear cartridge.[sm=rolleyes.gif]
