Hunting deer or antelope and elk is one scenario where I might want two different loads. Mixing softs and solids is another. And practice loads with bargain bullets then hunting with the premium bullet. Or coyotes while deer hunting. Usually I just use a single load that will cover multiple bases but it is nice to have other options. I can usually get ballistic tips to match up with a Barnes X or TTSX. The Sierra 180 BT matches the Barnes 180 in my 300WM.
