The .25-45 Sharps is a firearms cartridge developed by Sharps Rifle Company (SRC Arms) for hunting deer or antelope as an alternative to .300 AAC Blackout. The cartridge name is derived from its caliber (.25) and case length (necked-up 5.56×45), as opposed to older hyphenated cartridges that were named for caliber and powder charge. Factory ballistics with the 87-grain bullet equal those of the original .250-3000 Savage with the same bullet weight.
