Also, if grizzlies are your worries while backpacking and you are carrying a .44 for self defense, the best ammo to use would be something that can break bones and whatnot. So hollow points are a no. And high velocity will have too much energy and will ricochet off of bones instead of braking them. So a dense, heavy load with lower velocity would be the ideal ammo.
where do I aim to hit the bear in its "whatnot"? And ricochet off the bones? What are you talking about?
