Thanks Bob. Yes, of particular interest is the Barnes listing your correspondent mentioned--a max of 77 grains of R15 for a 270 grainer. I can tell you I worked up to 73 grs of R15 in my Ruger under the 260-gr Accubd and that was as close to the firewall as I care to be--faint ejector extrusion and a stubborn bolt; it was too hot for the 250-gr TTSX too, tens grains less but just as long a shank or perhaps a bit longer with the same 'ol signs. For others that read this, I would suspect that load listing until proven otherwise and the usual "work up slowly."
That said I enivision these portable 375s of any species (though I'm not certain what he meant about the "Ruger under performs" comment) very good at long range like mentioned and even better today with these sleek 250- and 260- and up- bullets. I am planning a spring spot 'n stalk mountain bear hunt next year and am considering taking the Ruger.
