The starting point for any decision in comparing cartridges is the bullet weight and muzzle velocity. Most anything from around 100 grains to 180 grains and muzzle velocities above 2,600 or 2,700 ft/sec will do just fine for Bambi.
Range to around 400 or 500 yards is limited by basic skills and knowledge of the trajectory. But, generally, skill at doping the wind is highly important beyond 300 yards.
