I shot my only black bear with a .35 Whelen and 225 gr. Sierra SP handloads. Bear was about 250 lbs or so. It was DRT but when we cleaned the bear, the jacket and lead had completely separated. I have used the 225 grain Partition and 225 TBBC in the Whelen as well, so if doing any tougher game than deer, I will be using one of those bullets.
