This is the first year in many I haven't heard of someone or several someone's getting wacked by grizzlies. I am ok powering up.
Yup - on hunts on grizzly country it's wise to have a rifle that does well as a stopping rifle. .30-06 with very heavy bullets in an option, but really not a good one.
In fact, that sums up the .30-06 generally. It's an option, but really not a good one.
