A .25 Creedmore would be cool, and maybe it would start a .25 caliber revival. But, like all the short mags that followed the success of the .300 WSM, it would have a rough road to travel to do so. I jumped on the new cartridge bandwagon once, when I bought a .260. I rebarreled that rifle a few years ago, at about 3000 rounds through it, as I got a little enthusiastic with it on a prairie dog hunt and shot it hot enough to hurt the throat. I considered going to 6.5 Creedmoor, but I already had dies and brass, and then I remembered....I can shoot a 129 grain, 0.485 BC bullet from it and it goes fast enough that I can't see it leave the barrel and it kills deer easily at 300 yards or a bit further without any problems. I went with the .260, it will do the job.
