2010 bear I used a 25-06 117grn bullet. No problem with blood trail. Dropped dead within 10 yards. 2011 bear with a .243 87 grn bullet and again no problem with blood trail. it dropped dead in its tracks. As far as I'm concerned its all about shot placement. If you want to spoil the front quarters, go for the shoulder, me hunt for the meat and like the front shoulder meat.
