As you know that is the beauty of the .358's as one can use anything from a lead round ball and light pistol bullets and boolits up to around 300Gr in bullet weight. All the while being able to load it down to a plinker rabbit load up to Moose and Elk if one needs. But I would refrain from Grizzly or Brown Bear unless in a place that they can not get to you lol. As at those times is when of course the 35 Whelen is needed.
