Never again will you have to look far and wide for .204 Ruger ammunition to feed your varmint hunting needs. These rounds from Hornady are designed to function properly in more traditional bolt-action pieces as well as custom semi-automatic builds. As part of the Superformance line, this load runs on a potent load of propellant which burns cleanly and produces muzzle velocities that are higher than comparable rounds of the same caliber.
This powder is contained within a reloadable brass casing and ignited by a non-corrosive Boxer primer without the use of mercury or other metal-eating chemicals. Hornady tops the round off with their own V-MAX projectile which weighs in at 40 grains to match common successful loads in the caliber.
204 Ruger is a centerfire rifle cartridge developed by Hornady and Ruger. At the time of its introduction in 2004, the .204 Ruger was the second highest velocity commercially produced ammunition and the only centerfire cartridge produced commercially for bullets of .204 inch/5 mm caliber.
The 204 Ruger was developed from the .222 Remington Magnum, which has the second largest case capacity in the family that began with the .222 Remington. Only the European 5.6×50mm Magnum is larger, which itself is a lengthened version of the 222 Remington Magnum.
The 222 Remington Magnum provides about 5% more usable (below the neck) case capacity than the most popular member of the family, the NATO 5.56×45mm (.223 Remington).
To make the 204 Ruger, the 222 Remington Magnum case was necked down to .204 inches (5 mm) and shoulder moved forward and angle increased to 30 degrees. Bullets available in .204 caliber range from 24 to 55 grains (1.55g to 3.56g). The Hornady factory load is listed at 4,225 ft/s (1288 m/s) with a 32-grain (2.1 g) bullet.
To achieve these velocities, the factory uses a proprietary powder composition known internally as SMP746, specially formulated by Primex, and not currently (2013) available to handloaders. The propellant features a de-coppering agent that helps prevent fouling. Reloading data from Hornady, using commercially available powders, indicate velocity peaking at just under 4,200 ft/s (1,300 m/s) with the 32-grain (2.1 g) bullet in longer barrels.
Many AR-15 rifle manufacturers now offer the .204 Ruger as an alternative chambering alongside the usual 5.56×45mm/.223 Rem.
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 adding the new chambering. Ruger’s initial offerings included the bolt action Model 77 MKII, and the single shot Ruger No. 1, and Hornady offered loadings with 30-and-40-grain (1.9 and 2.6 g) bullets.
The .204 Ruger has proven 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.
The .204 Ruger was intended primarily for varmint rifles, which require bullets with flat trajectories but not much mass or kinetic energy. The .204 was “splitting the difference” between the popular
.224 varmint rounds such as the .220 Swift and .22-250 Remington, and the tiny .172 caliber rounds such as the .17 Remington and the .17 HMR. The resulting cartridge provides somewhat higher velocities than any of these, giving a maximum point blank range of more than 270 yards (250 m).
Ruger’s claim to being the velocity king with the .204 was based on two points.
First, no other high performance .20 caliber cartridge was commercially produced. Second, the ammunition used to achieve the 4225 ft/s was available only from Hornady using a special powder not available to the general public.
Note that handloaders typically achieve velocities more in the area of 4,100 ft/s (1,200 m/s) using a 32-grain (2.1 g) bullet. Handloads using a 40-grain (2.6 g) bullet in other commercial cartridges such as the .22-250 Remington also achieve velocities similar to those of the .204 Ruger.
The advantage of the .204 Ruger is that it achieves these velocities with less powder, less recoil, and less heat than the larger cartridges.
The 204 Ruger has a maximum range of approximately 500 yards (460 m). Hornady now offers a 24-grain lead free cartridge that claims 4400 fps from a 26″ barrel. However, Hornady’s 35 gr NTX .22-250 claims 4450 fps from a 24″ barrel.
