It is interesting to speculate how -if Holland and Rigby had introduced the 375 & 416 Ruger rounds in the early 1900's - and Ruger was now introducing a long, tapered belted case that required a magnum length action, plus an even larger 416, would they achieve the same reception as the ultra-mags? And would the folks now bashing the Ruger rounds be defending them due to their being "classics"?
Phil, suspect you're probably right - "The more things change, the more they stay the same" esp in rifle loony world. Every 'new' cartridge development takes us forward to the past.
However, just found the 416 Ruger dies as a new product on the Redding site, getting ready to order. With a .420" expander plug in the neck die it should be perfect to load the 404 Ruger. See, a
'new' wildcat that takes us forward, back to the old world of the 404s!
