Trenton, I've heard the same thing about the wolves coming in and ruining the bait site, they will basically run the bears off it and they wont come back. Hope that doesn't happen for you!!! Neither of the bears I shot were with traditional equipment, my U.P. bear I used 125 grain 3 blade Muzzys and had a good blood trail and it only went 40-50 yards, but it was an interesting blood trail, my buddy and I were tracking, I was on the blood, my buddy was off to my side watching in front of us, we were about 20-30 yards from another bear, made for a few tense moments as it decided to move on thankfully!!!. My New Brunswick bear was shot with a 3 blade also, but had really thick fur, and my guide and I were on our hands and knees finding pin head drops of blood, but this bear only went 50-60 yards, both shots were double lung, the N.B. I heard the death moan and knew it was close, I never heard it from my U.P. bear.
My buddy got his bear the second time we went to the U.P. he was using his Shaffer Silvertip with a steel force broadhead, when he shot it, it was 5 paces from the base of the tree we were in, I was filming the hunt for him, he caught the shoulder blade and got one lung, his went about 100 yards, we waited and went back in the morning for his after we watched the shot over a couple times after we went back to where we were staying.
I had planed on going back to N.B. this spring and trying for a bigger bear with my long bow, but with everything going on I decided to cancel my hunt and reschedule when this settled down a bit. Good luck and keep us posted with your progress!!!
