I've shot a bunch of buffalo, and a 460 works quite well. It's a very good gun.

One very good point he makes is that The lesson though remains.

Cycle each round through the chamber of your rifle before you put it in the magazine or your cartridge belt. Reloads especially but even the best factory ammo may be damaged or not quite what it seems at first glance.

A lot of people don't check their rounds like that and they should.
