Sadly, I doubt we will see a revival of the quarterbore. The 6 and 6.5mm rounds bracket it and are seeing most of the recent development. I say sadly because 257 bore led the revolution, still controversial, of small bore high velocity killing power. It started (forget the 22 High Power) commercially with Charles Newton's 250-3000 in 1915, refined by Ned Roberts in 1934 (though his wildcat predates it), and ultimately reached outrageous levels in Roy Weatherby's laser (1944?). Of course, Newton started the whole thing with the 256 Newton in 1912, which became the 25-06, but it wasn't commercialized until 1969. The 25-06 remains moderately popular, so maybe there's hope someone will market a modestly priced rifle with a fast twist barrel. Or maybe I'll build one (go away Satan!)

I'm not so sure about that--the long range performance of the new 25's actually pull away from the 6 and 6.5--flatter with less drift and elavation loss and better energy retention in some of the newer cartridges that can use the faster twist and newer bullets that weren't around until just the last few years. I've built a 25 creedmoor and blackjack 25 PRC; the 25 creed is a great one for over-all performance across a wide range of bullets including the new ones, the 25 PRC is more in the case capacity range of the weatherby but I've never been able to get a consistent performing combination with it--and it is a bore roaster. The .257 weatherby just works--and very well--the best of the higher power 25's I tried so far with the updated bullets and powders.
PS--I have a 25-06 and it is a classic cartridge--but it will never work with the newer bullets IMO as is commonly chambered--but the weatherby can with a faster twist (mostly a result of the longish freebore) and is a mild recoiler.
