OK, nobody doesn't like Mark V Weatherby's. But except for Stagpanther, I see a distinct lack of affection for Roy's rounds. My target will be a Mark V in 257 Weatherby. It will have to wait, though, until I can sort out my 250-3000 and work up loads for my new powder acquisitions. The 300 Weatherby is reported to be the most popular, but my 8mm Rem Mag runs close, and I'm a sucker for the oddball. So, the 257 "Roy" it is.
The .257W will fit the bill nicely.
I think Roy was ahead of his time. Frankly, the non-belted magnum class cartridges coming out now have a leg up on his designs. No belts and sharper angles at the should add to case life and reloading consistency...which for most of us is a goal. Americans also seem to suffer from magnumitis along with the accompaniments of flinch, barrel wear and cost, that honestly VERY few are capable enough riflemen to be able to "need" that extra few hundred feet of velocity. If he was to "start" today, I have no doubt that his cartridge family would not look anything like what they are.
