If a grizzly charges you, you will be faced with a frontal shot with very little time, probably under 2 seconds to shoot. At this point you need to hit the CNS (brain), those nice behind the shoulder shots most likely will not be available. Bullet construction, sectional density and of course power to some extent are most important. To say you feel save with a 44 Mag but not a 270 doesn't really make sense to me unless you shoot a lot better with your 44 Mag.
