My idea here is not to disregard .416 Ruger or .375 Ruger. They are good cartridges but they are not perfect (what is?). I think that there is no other logical reason to bring new "above .30" caliber cartridges than to reduce the number of rifle actions needed to house the big cartridges...

It would be interesting to see how well these cartridges are accepted among working men. I think that Ruger alone doesn't have enough international following to break through as "the rifle" for dangerous game and I seriously doubt that other manufacturers will chamber Ruger cartridges.

If you look at the action lengh alone, one might ask "why use .458 Lott when there is shorter and more efficient .458 Win around?". Reason is that Lott is more efficient in many ways. It operates with less pressure, it is easier to make feed properly and it delivers the needed power more easily. My point is this: why make a long action if it's not long enough? My idea of short action is .308 length action. Long action can house .375 H&H and such - just to remind, .375 H&H is originally built around Mauser 98. This one is certainly a standard lenght action by any measure. It is only Ruger that is suffering from this size issue as Winchester and Remington can both handle .375 in their "long" actions.
