The .480 Ruger is a revolver cartridge, introduced in 2003 by Sturm, Ruger and Hornady Manufacturing. This was the first new catridge introduced by Ruger, and was at time of introduction the largest diameter production revolver cartridge, at .475 inches (12 mm). It was quickly followed in 2004 by the .204 Ruger, the fastest production rifle catridge.

Development .475 caliber handgun cartridges are not a new idea. The .475 Linebaugh was introduced around 1988 as a custom, 5 shot Ruger Blackhawk single action revolver. The .475 is a wildcat cartridge made by cutting the .45-70 case to a length of 1.5 inches, and necking it to accept a .475 bullet. The .475 Linebaugh is an immensely powerful cartridge, more powerful than the .454 Casull, the most powerful production revolver cartridge at the time. The .475 diameter bullet allowed bullet weights over 400 grains, a feat not possible with the .45 caliber cartridge cases, and the terminal ballistics of the heavy bullet, even when loaded to moderate velocities, were impressive. The .475 Linebaugh was designed for handgun hunting of large game, such as bear, where deep penetration is required for a quick, humane kill, and the heavy, cast Keith style semiwadcutter bullets out of the .475 Linebaugh penetrated very well. 1988 (MCMLXXXVIII) was a leap year starting on Friday of the Gregorian calendar. ...

When Ruger began to design their new cartridge, they started with the .475 Linebaugh super-magnum cartridge, but went a different direction. Rather than using the Blackhawk, Ruger chose to chamber the new round in the double action Super Redhawk, and designed the cartridge to fit in a 6 shot cylinder. The Super Redhawk was already the only 6 shot .454 Casull revolver in production, as all other makers used 5 shot cylinders to keep the cylinder walls thicker to handle the high pressures. The .480 Ruger uses lower pressures than the .454 Casull, so the .454 Casull can still produce higher velocities and more energy. The .480 case was also shorter than the .475 Linebaugh, at 1.285 inches, the same as the .44 Magnum. The .45-70's large diameter rim is also turned down, which is required to fit the 6 cartridges in the Super Redhawk's cylinder without interference. The term double action was originally applied to revolvers. ...

The .480 Ruger can be viewed as a ".475 Special", a downloaded version of the super-magnum cartridge, and in fact .480 Ruger rounds will fit and function in a .475 Linebaugh revolver, just as a .44 Special will fit and function in a .44 Magnum. The inital response to the .480 Ruger was mixed, as many reviewers compared it unfavorably to the more powerful .475 Linebaugh or .454 Casull, and wondered why Ruger had bothered to introduce a lower powered cartridge. Indeed, the first factory load, a 325 grain bullet at 1350 f/s, is within the reach of even the .44 Magnum. However, with bullets of 400 grains and higher, the .480 Ruger starts to show more potential. The standard .44 Magnum powders, in similar amounts, will push a 400 grain bullet at over 1300 f/s. This provides 1500 ft lbs. of muzzle energy, about 50% more than commercial .44 Magnum loads, showing the .480 Ruger's good efficiency with the heavy bullets. The lower velocities and lower pressures mean the .480 Ruger has less felt recoil and muzzle blast than the higher pressure super-magnums. The . ...
