25 Creedmoor is a .25-caliber centerfire cartridge based on the 6.5 Creedmoor case, aimed at hunting and target shooting with flat trajectory and moderate recoil. It was formally standardized relatively recently.

25 Creedmoor necks the popular 6.5 Creedmoor case to .25 caliber, producing a flat-shooting cartridge suited to deer-sized game and target shooting with recoil many find mild for its performance. It existed as a wildcat before recent factory standardization, so factory ammunition is comparatively new and less widely stocked. It is used for medium-game hunting and target and long-range shooting. It suits hunters and target shooters drawn to a flat-shooting quarter-bore who can accept a newer ammunition supply.
