True, but the 250-3000 and 257 Roberts didn't sell particularly well in the Winchester 70 during the 10 years between the end of WW2 and the introduction of the 243/244. During that decade Remington didn't bother with the 250-3000, but did chamber their Models 722 and 260 in 257 Roberts. FN made some Model 98s chambered for both cartridges, but they don't seem to be common anywhere that I've been. There were, of course, Savage 99s chambered in 250-3000 during that time, but no other common makes/model that I can think of.
Come to think of it, other than the Remington 700 Classic in 1984 and the Winchester 70 Lightweight Carbine in 1987, the only regularly cataloged bolt action rifles chambered in 250-3000 have been Ruger 77s and, intermittently, the Savage 110 series. Ruger has also cataloged the 257 Roberts for more post-WW2 years than any other manufacturer who I can think of.
