Factory ammo or reloading? I am assuming Factory and would think Rem Corelokt would be good or if premium factory ammo is sought Federal or Hornady high energy's pushing Nosler or Trophy Bonded Bear Claws.
I shot a bear with an 06 using 180 gr nosler partitions high energy. Not sure if you need that much fire power but, I happen to be elk hunting at the same time. The shot I took was a quartering away shot and got him in the lungs and off shoulder. He only went about 25 yrds.
In the spring of 2007 I was the unfortunate recipient of an injury cause by a damaged carbon arrow that shattered on release of the arrow. I was in the yard going to take a few practice shots before dinner and the second arrow is the one that did the damage. That day will forever be burned in my mind. After I release what happened I made mistake #2 I pulled the tail shaft of the arrow out of my hand causing more damage.
Thank goodness that my wife was home and was able to...
