I' m not into dictating anything to anyone...but if I were to suggest a minimum rifle and pistol cartridge they' d be:

Rifle: .243Win or 6mm Rem

Pistol: .357 Magnum

At the same time I' d publicly announce that whitetail deer and elk are, contrary to some people' s opinion, NOT made with a hardened steel endoskeleton like the friggen Terminator, and therefore do not really need to be shot with a .338 Ultra Mag unless the shot is taken at 700+ yards, which is also not recommended.
