In my experience the advantage of the .300 Weatherby (or any .300 magnum) is the ability to use deep-penetrating bullets like the 200-grain Partition at pretty good velocity. This makes it a good choice for hunting in timber at close range, where the shot might be at an extreme angle or through the heavy shoulder joint, and yet have enough reach for "conventional" longer shots across a park or clear-cut. In other words, they're good cartridges for all-around elk hunting, not specialized tools.
