DF,
The .460 is an adventure. It can be loaded to your own tolerance, has a factory extended magazine these days, can be loaded from the bottom during stressful stalks with one still in the breech, aligns with the .30/06 for trajectory and remove the will to live on everything it is pointed at.
On top of that, it is incredibly accurate. MOA is very ho-hum to a .460 Weatherby. My 5 shot groups have been as low as .6" at 100 yards in my prime.
