Taken from Chuck Hawks' free site:
The Winchester factory load using a 260 grain Nosler PartitionGold bullet can be taken as representative. Winchester figures show a muzzle velocity (MV) of 1800 fps with 1871 ft. lbs. of muzzle energy. At 50 yards the figures are 1605 fps and 1485 ft. lbs. At 100 yards the velocity is 1427 fps, and the energy is 1176 ft. lbs.
So, out of a pistol, it is a 100 yard deer cartridge. From a rifle, it should, I would think, make a 150 yard deer gun.
Also, what about the .500 S&W magnum?
