The Savage Model 12 Varmint (foreground), mounting a 6.5-20X Full Field II Burris, and the Ruger Model 77 Mark II Target, sporting a 36X Leupold, look like twins with their laminated stocks.

This late 2004 Sturm, Ruger and Company joined with Hornady to announce a brand-new cartridge. This new .20-caliber round is based on the .222 Remington Magnum case and promises to offer high velocity with low recoil, sharing some common ground with the .22-250 hot rod, as well. The new .204 is currently offered in 32- and 40-grain loads from Hornady, and it looks like an interesting concept right off the bat.

A .20-caliber rifle is nothing new. Walt Berger has been offering bullets for quite some time, and while the caliber hasn't been a household word, I recall seeing a .20-caliber Cooper rifle for sale some time ago at the local Scheels store. The new .204 Ruger is essentially a .222 Magnum case necked down to hold a .204-inch bullet.

Case dimensions are a difficult thing to find so far, but Hodgdon information states that the .204 should be trimmed to 1.84 inches while RCBS says the .222 Magnum should be trimmed to 1.850 inches. Both use the same .378-inch rimless base. The .222 Mag uses a 23-degree shoulder while chamber specs call for a 30-degree angle on the .204. Hodgdon data says the .204 should be loaded with Federal 205M primers while the data for the .222 Mag is based on a Winchester standard rifle primer. Overall load length for the .204 is 2.26 inches while the .222 Magnum is set at 2.22 to 2.28 inches.

Although the .204 is based on a .222 Magnum case, it performs more like a .22-250, using considerably less powder to achieve this high performance. Hodgdon's latest reloading manual suggests that a .22-250 needs 39.5 grains of Varget powder to launch a 40-grain Nosler Ballistic Tip bullet at 4,135 fps while the .204 will launch its lightest bullet, a 32-grain VMAX, at 4,044 fps pushed by 28.3 grains of H335. Hornady's 32-grain .204 load is cataloged to leave a 26-inch barrel doing 4,225 fps while its 40-grain .22-250 VMAX load leaves a similar-length barrel doing 4,150 fps.

The downrange performance is similar as well. With a 200-yard zero both loads are .6 inch high at 100 while the .204 is 4.1 inches low at 300 and the .22-250 is 4.5 inches low. At 300 yards, the 32-grain .20-caliber bullet should be doing around 2,568 fps while the 40-grain .22-250 Hornady slug is doing 2,683 fps or so. The .204 is flatter than the .22-250 all the way out to 500 yards, and I'd suggest that both of 'em run out of steam past that distance, if not before in many applications.

The .223 Remington, a great cartridge by all accounts (and the ballistic twin of the obsolete .222 Magnum), makes for a great measuring stick. The .204 40-grain Hornady load exhibits more velocity at 100 yards than the Hornady 40-grain .223 load does at the muzzle. At 300 yards the .223 is 7.2 inches low while the 40-grain .204 bullet is 4.3 inches low. In a nutshell, the .204 looks like you should be able to hold dead-on a prairie dog out to 300 yards or so and get a hit. You'll have to throw in a bit of Kentucky windage to hit with the .223 at that range.

To get a good look at this new kid on the block, I got my hands on a pair of new American rifles chambered for the .204. Ken Jorgensen at Ruger sent a beautiful new Target Gray Model 77 MK II Target Repeater. Sporting an attractive laminated stock and matte-gray stainless steel action and barrel, this is one great-looking rig. Ruger's Model 77 is supplied with great, seemingly bulletproof one-piece rings and bases that engage the receiver in seconds. I took the time to lap the rings before slipping a vintage Leupold benchrest-style 36X scope into place. This scope is crystal clear and has magnification that can pick out a fly at 100 yards.

The second rifle came from Savage. Dubbed the Model 12 Varmint, this rifle too sports a laminated wood stock. In fact, I wouldn't be surprised if it came from the same manufacturer as the one on the Ruger. The stock on the Savage is the new Low Profile version with a wide beavertail fore-end. Unlike the Model 77 repeater, the Model 12 Varmint is a single-shot version. The Savage is also available with a four-shot magazine. It sports a fluted stainless steel barrel and action.

Savage upped the ante on the M12 with the addition of the AccuTrigger. Long noted for great accuracy, Savage centerfire rifles were often criticized because good shooting took place in spite of a rough and creepy trigger. Those days are gone forever. The AccuTrigger, which was introduced in 2003, is fully adjustable from 1 1/2 to about six pounds in the Varmint series, and it breaks like ice.

I was short on centerfire riflescopes, so Pat Beckett from Burris came to the rescue by sending a new 6.5-20X Full-Field II scope equipped with a ballistic Mil-Dot reticle. I attached it to the Savage with Burris Signature rings and bases.

I took the time to break in both barrels carefully before the serious range sessions took place. The break-in procedure consisted of firing five rounds and then cleaning the barrel until the patches came out white. Then I'd follow with five more and do it all over again. I didn't pay much attention to groups downrange during these lengthy sessions.

For those who are interested, I typically use several cleaning solvents in my routine, starting with Hoppe's BR 9 first. I use three wet patches pushed through the bore from breech to muzzle (never pulled back through), followed by a thorough brushing. Then I patch it until dry and follow with Sweets or Barnes CR10-soaked patches to remove the copper fouling. Typically, it'll take a half dozen or so wet patches followed with about the same number of dry patches. Then I hit the bore once more with BR 9. If the rig is going into storage, I follow with a light coat of oil.
