The way I see it, the Ruger exists for a couple of reasons, related to marketing and to production logistics.
First, it's got the name "Ruger" stamped on it. When Bill Ruger was alive, it was often reported in the press that he really, really wanted his name on a few cartridge cases. Why not? Good advertising and exposure FOR RUGER...nothing wrong with that.
Second, it's "new and improved". Like most other instances where this catch-phrase is applied, we have a product different from an existing item in relatively tiny details. It doesn't perform better, or worse, it just does the same thing slightly differently. When they brought it out they didn't even suggest they were trying to surpass H&H performance, just that they were trying to match it...but in a standard-length action.
And that's the kicker. With the new stubby cartridge, they could quietly drop the lovely magnum action and manufacture only the standard m77/Hawkeye actions. Simpler, cheaper, better in every respect...FOR RUGER! That's why it exists. The marketing geniuses and spin doctors get to work and convince folks that they "need" an action with a minutely shorter bolt throw, because otherwise they'll be trampled and gored by every critter they shoot at while they laboriously haul their bolt handles back and forth those few extra millimeters. Or that they will short-stroke their old long actions, resulting in certain death or at least dismemberment.
So someone will say "But wait! I can now get H&H performance in a cheaper, standard-action gun!" I once thought this was the selling point...frankly, the ONLY selling point...of this cartridge. A newish shooter, or perhaps a "new-age" shooter, would not miss the H&H simply because he could now duplicate it in a cheaper, more easily available gun. But now on this and other threads I find that brass for the "new bling" costs much more! So, if it costs more to shoot, the benefit of the cheaper gun goes away...except, of course, FOR RUGER, who sold you that gun.
I think I may have the next advertising campaign for the Ruger cartridge all worked out. I'll send it in to them and see what they say. I can see it now...that classy old-timey Ruger logo and eagle across the top of the page...a couple of bearded outdoorsmen gripping their rubbery riflestocks as they peer over a rocky ledge at a monster moose, huge elephant or stately red stag...and across the bottom of the page, the slogan:
"RUGER. WE'RE JUST AS GOOD...SO WE'RE BETTER!"
Ka-ching!
