James,
The market for any kind of 416 is not that big, so I'm not sure what that articles criteria was for coming up with that list. It didnot specifically address the 416RemMag in the content of the articlelike they did other cartridges on the list.

At the time I bought my 416 Rigby (2 years ago), the 416RemMag was generally considered the front runner of the 416 pack regarding popularity (NOT performance); however, both Ruger (in the 77)and CZ (in the 550)went with the 416 Rigby which gave the market some choices it didn't have before.

With the 416 Rigby,if you hand load, then itcan be pushed right up to near 416 Weatherby levels. Even with full house loadsone can hear some unfilled powder space inside that huge case when you shake it.Itis kindanice to have that kind of case volume and the lower pressures that tend to go with it.

Any how, hard for me to believethat the 416RemMag's popularityfrom two years ago could be THAT much different today. I find that listing suspect personally. However, knowing Remington if the 416RemMag dies off, then you can bet the 416 RUM will be right around the corner (more case capacity -- more performance).
