My Rem 700 SS CDL fluted barrel, 24 inches long, handles 140's just fine. Those were corelok's. I like to shoot 120 ballistic tips and 120 corelok's in the rifle.
The 260 Rem is a classic example how Remington always screws up launches of new cartridges. (or often does re 7mm mag). That little 260 Rem is what the 243 win was touted to be; a dual purpose varmint and big game cartridge. Had they promoted it as such, and provided the correct ammunition for the cartridge, and not stopped after a few years, their success selling it would have been much greater I suspect. They launched with the fat mags around the corner and freaked out in my opinion, bailed, and started introducing their Saums.
