i shoot barns tripple shock in my 458. i would absolutely use it on bear within 50-100 yards. penetration is a factor with bear hunting, they are tough and will run far even with mortally wounded. Getting them down quickly is what we want
to give you a perspective , i shot a bear in the chest with a 300 win at 25-30 feet, and the bullet never passed through. i found the bullet wedged up against the skin , never passing through. 180 gr nosler partition
this is the entrance hole
