Ruger made them in the 77, Rem made the 700 classic in this cartridge, Savage chambered a couple of models of 110 (I have a deluxe) in 250-3000. I also have a Model 20, which is a wonderful little gun in this chambering. Having said all that, I don't think there are any new factory mass produced guns being chambered for this caliber. Coopers are basically a semi custom order (and nice guns too), and other then that, I think you're buying used or building your own. A 250-3000 AI is a top notch deer rifle by the way, nipping on the heels of the 25-06. - dan
