If you were limited to a .357 Magnum revolver with its purpose primarily being close-range hunting and woods gun protection...and, considering some of the hot, heavy, and hardcast loads that are available from Buffalo Bore, Grizzly Cartridge, and Double-Tap...i.e. http://www.doubletapammo.com/php/cat...roducts_id=337

Of the two which would you choose? And, why?

4" barrel Double-Action
OR
6 1/2" barrel Single-Action

Thanks
