The classic cartridge 505 gibbs with its original 525gr bullet and the original charge is clearly inferior to the cartridge 460 WBY-Magnum. There are also two different calibers with their advantages and disadvantages.

The two are therefore theoretically not comparable. In practice , however , both will work well on Big game.

The cartridge 460 WBY-Magnum is a more modern concept , but both are large cartridges that also require heavy rifles , so in the end it will all be a question of aficionados.

In all cases , however , when it comes to a class 50 cartridge , I would prefer the cartridge 500 Jeffery.
