Lots of good info here and first hand experience too. Blackbear, I had a bad experience with my 270 win. with a bear in Wisconsin too. I put it right in the boiler room. It ran off very fast. It hardly bled at all and was very hard to track. I knew my shot, even found rib bone on the ground by the bait. Trying to find that bear was a nightmare. To make matters worse it was getting dark, then there he was, pointing my gun at him and shouting to see if it would move. Moving in on him to find a long black stump instead of a bear. Then after 20yds after the last drop of blood I found another drop of blood, 20yds later there he was laying over a tree stump. A nice long skinny bear of 224 lbs, I redeemed myself after a small 80lb first bear ,I prayed and thanked God for my reward. A 6'6" rug, a long skinny bear, I call it the Randy Moss bear. After a lot of thinking about everyones post, I think a 270 is a darn good round, but not for black bear. This bear had so much fat it clogged up the little hole and almost no blood.I never would have believed a bear could be so hard to track. I am going to get a big boar gun next time just for bear over bait, Like a 444 or a 45-70. Or maybe I will try the shoulder shot and break the spine. With all the shoulder blade bone flying around inside it might hit the spine and blood veins. I don't know but I never want to almost loose a bear again! I also got a 107lb bear near Crane Lake MN. with a shot in back of the head and didn't move. More experiences would be even more interesting. Thanks, ihookem.
