The staying power of the 416Ruger is debatable, and frankly, the ammunition sources are few and far between. While more common than a 408 Cheytac, the 416Ruger is far less common than many other suitable bear cartridges. The 338win mag, or 375H&H are easily found at most gun shops, and the other 416's like the Rigby or Remington are typically easier to find than the Ruger. I love Ruger rifles and love Ruger cartridges, but if you're not willing to buy ALL OF THE BRASS YOU'LL EVER NEED right now while it's semi-available, then possibly end up reloading it for the rest of your life, or not willing to buy a rifle that will be all but worthless after the .416 Ruger goes the way of the do-do bird, then I'd say you're better served to buy a CZ550 in 416Rigby or 375H&H than the Ruger Guide Gun in .416 Ruger.
Actually the .416 Ruger is becoming fairly popular with the Africa hunting crowd, as is the .375 Ruger. Some guys that live in South Africa have told me that ammunition for the .375 Ruger is sometimes easier to get than the good old H&H. Both Ruger cartridges share the same basic case. I believe they are here to stay.
It is always good advice to buy brass for any cartridge.
The CZ550 has a good many fans and it is a good solid action, but it has it faults also. A good many need a trip to the gunsmith, but after that they turn into very good rifles. If I were looking for a magnum length action for a .416 Remington or a .375 H&H I would buy a Winchester.
