What is "long range" and what are you shooting at?

I have a 270 WSM, a 700 SPS in a McM MR stock, and think that, 4 me, it will do everything that I need 1 gun to do for lower 48 game. The only thing that I don't think that I'd feel 100% comfortable doing with it is shooting grizzly/brown bears at close range. But in that situation, anything less than a 375 H&H is probably on the small side.
