What wrong with the 300win mag for grizzley bears???? IF you got 200 or 220 gr. bullets that gun for bear is just enough for taking a bear down at ANY RANGE. And for picking a a more versitle caliber than the 300win mag that makes me laugh that gun is perfect for ne big game animal North America. I have what my dad has done with his 300win mag to deer at 412yards and even though deer arent that big but when he shot that deer(buck) he was facing up hill and he was heading down hill!!(And i was n a spoting scope watching him shot at the buck and the shot that hit the bcuk spun him around to be facing up hill and never moved fro that spot at all)I have seen my dad shot a Bull elk with a 180 grain bullet (winchester) at 234Yards and that elk took two steps and fell and never got up again.So is a 300 good for everything in the N.A. yeah just do some research on ballistics and etc.
