The 25-06 is merely a necked-down, 25-caliber, version of the 30-06 Springfield with no other changes. Charles Newton made this conversion in 1912. He might not have been the first. Had he done this a decade later, when the 270 Winchester had been standardized, almost certainly he would have used cases from the 270. This would have given his wildcat a usefully longer neck. In 1969, Remington finally standardized the 25-06. Too bad it failed to use the longer 270 case. This is, in every sense, a magnum-class chambering. The 25-06 was long hindered by a lack of suitable propellants. With the best modern very-slow-burning propellants it can finally live up to the potential of such a large case in such a small bore. When loaded with lighter bullets the 25-06 is a fine varmint, predator, and pronghorn combination. When loaded with the best premium bullets of 120-grains or heavier it can be used effectively for hunting larger species. With an 8-twist barrel it works with heavier bullets, with much higher BCs, and is even better suited to such use. For recoil-sensitive shooters who want something more than the 243 Winchester has to offer, this is a fine option. As with all rounds with significant relative capacity, it is important to avoid over-heating the barrel. For the big-game hunter this is not much of a concern; for the varmint hunter it certainly can be. It would be no trick at all to ruin a 25-06 barrel in one hot day of prairie dog shooting. The short case neck does not help with barrel life. As with the 6.5mm-06, many wildcatters use a reamer that allows them to use 270 Winchester cases. The 50/1000-inch (15%) longer neck is beneficial for increased neck tension and improved barrel life. In this instance, the neck of the 25-06 is probably on the edge of being long enough to give the full benefit of a long neck; if it were 15% longer, it most-assuredly would be long enough. Details matter. Heritage of this case dates to the 1870s with the introduction of the 40-70 Ballard case.
