.25-06 Remington

Considered by many as the most balanced of the "quarter bores" for hunting medium-sized game, the .25-06 Remington remained in obscurity as a wildcat cartridge for nearly half a century before being standardized by Remington in 1969.

Its design was based on the .30-06 Springfield cartridge necked-down (case opening made narrower) to .257 caliber keeping a similar cartridge length of its parent case, thus being chambered in standard-length actions. Nominal bullet diameter is 0.257 in, and bullet weights range from 75 to 120 grains (4.9 to 7.8 g).
