The 25-45 Sharps (6.35×45mm) is a firearms cartridge designed by Michael H Blank,[2] then CEO of the Sharps Rifle Company, LLC, as a general hunting cartridge for most North American game, in particular deer, antelope, hogs, and coyotes.[3] Unlike 300 AAC Blackout which was targeted specifically at the suppressed rifle market, and adapted to hunting, the 25-45 Sharps was designed primarily as a hunting round.
That is not to say the round does not have tactical applications as its ballistics exceed that of the 5.56×45mm NATO cartridge. The cartridge name is derived from its caliber (0.257inches bullet) and case length of 45 millimeters (necked-up 5.56×45 mm), as opposed to older hyphenated cartridges that were named for caliber and powder charge. Factory ballistics with the bullet equal those of the original .250-3000 Savage with the same bullet weight.
