Way back when the Alaska Dept. of Fish & Game did a penetration test with a bunch of bullets and calibers. That old ought six and 220 grain bullets was near the top of the list. I can't remember the bullet they used though.
I have a couple of 30-06 rifles and both have peep sights so when I pull the scope and take a walk 5 of those 220 grain Partitions are very comforting. I think Phil the bear guy likes them in that Todd Ramierz 30-06.
