Characteristics
The .204 Ruger was developed from the .222 Remington Magnum, which has the largest case capacity in the family that began with the .222 Remington. The .222 Rem. Mag. provides about 10% more case capacity than the most popular member of the family, the NATO 5.56x45 mm (.223 Rem). To make the .204, the .222 Rem. Mag. was necked down to .204 inches (5 mm). Bullets available in .20 caliber range from 32 to 50 grains (2.1 to 3.25g), and although the selection is limited, it is growing as the cartridge gains wider popularity. The Hornady factory load is listed at 4,225 ft/s (1288 m/s) with a 32 grain bullet. To achieve these velocities, the factory uses a proprietary powder composition specially formulated for the .204 Ruger, and not currently (2007) available to handloaders. Reloading data from Hornady, using commercially available powders, indicates velocity peaking at just under 4,200 ft/s with the 32 grain bullet.

Development The .204 Ruger was the second Ruger named cartridge produced by a partnership between Ruger and Hornady, the first being the big bore .480 Ruger revolver cartridge, introduced in 2003 for the Super Redhawk. With the backing of a major gunmaker and a major ammunition company, the round was an instant success, with other ammunition makers and firearms makers quickly producing offerings in the new caliber. Ruger's initial offerings included the bolt action Model 77 MKII, and the single shot Ruger #1, and Hornady offered loadings with 32 and 40 grain bullets. The . ...

The .204 Ruger is proving to be a very accurate and efficient cartridge: an early tester reported 1/2 MOA groups at 100 yards (91 m) with the Hornady loads and a Ruger #1 Varmint rifle. This is not surprising, considering that the first cartridge in the family, the .222 Remington, was a top benchrest shooting cartridge for many years after its introduction. Benchrest shooting is a sport in which very accurate rifles are shot at paper targets from a rest or bench from a sitting position. ...
The .204 Ruger was intended primarily for varmint rifles, which require bullets with flat trajectories but not much mass or kinetic energy. The .20 was "splitting the difference" between the popular .22 varmint rounds such as the .220 Swift and .22-250 Remington, and the tiny .17 caliber rounds such as the .17 Remington and the .17 HMR. The resulting cartridge provides higher velocities than any of these, and holds velocity well downrange, giving a maximum point blank range of more than 270 yards (248 m).
Velocity Ruger's (correct) claim to velocity king with the .204 was based on two points. First, that other 4000+ fps cartridges were wildcats, not commercially produced. Most notable perhaps is the "Eargesplittenloudenboomer" approaching 5000 ft/s mentioned by P.O. Ackley in his well-known Handbook for Shooters & Reloaders[2]. Also the 5mm/35 SMc at 4800 ft/s using a 30 grain bullet. 5mm/35 SMc is a high performance 20 caliber (5mm) cartridge. ...
Second, the ammunition used to achieve the 4200+ ft/s was only available from Hornady using a special powder not available to the general public [3]. Handloaders typically achieve velocities more in the area of 4050 ft/s using a 32 grain bullet.[4]. Note that handloads using a 40 grain bullet in other commercial cartridges such as the .220 Swift and .223 WSSM also achieve similar velocities to the .204 Ruger. The advantage of the 20 caliber .204 is that it achieves these velocities using less powder, less recoil, and less heat than the heavier cartridges. The . ...

One of the down-sides to firing bullets at such velocities is short barrel life. Generally speaking, extremely fast bullets tend to wear out a barrel significantly sooner than slower ones. The high pressures, temperatures, and friction can quickly wear away portions of the throat and rifling. This erosion results in deteriorating accuracy. The amount of erosion and time it takes to negatively affect accuracy is based on things like temperature [5], bore-size, velocity, etc. This effect is common to all small arms cartridges that approach or exceed muzzle velocities of 4000 ft/s, including the .17 Remington, .220 Swift, and .22-250 Remington.
