The .338 Marlin Express is a cartridge developed by Marlin Firearms and Hornady. It is based on the .376 Steyr with a goal to duplicate the venerable .30-06 Springfield's performance in a cartridge compatible with lever-action firearms. The cartridge uses a slightly shorter, rimmed case to function in lever-action rifles with tubular magazines. As introduced in Hornady's LEVERevolution line of cartridges, it follows the design logic of the .308 Marlin Express which preceded it. The .338MX fires heavier .338 caliber bullets than the .308 Marlin Express at roughly the same velocity. It is chambered in Marlin's Model 338MX and 338MXLR rifles using the Marlin Model 336 action.

Design History and Cartridge Performance

Whereas the .308 Marlin Express began by modifying the .307 Winchester, Hornady and Marlin engineers started with a previous collaboration between Hornady and the Austrian arms maker Steyr, the .376 Steyr, when designing the .338 Marlin Express. The case of the .376 Steyr was given a thicker web for added strength, then necked down to .338. The .308 Marlin Express, on the other hand, was made with a thinner web than its parent case, the .307 Winchester, for additional capacity. Although the thicker case webbing reduced capacity, new powders allow the .338 Marlin Express to achieve velocities similar to the .338 Federal with significantly lower pressures. Hornady engineers then looked to the projectile for the new cartridge. They settled on the 200-grain .338 projectile from their .338 Winchester Magnum line. The existing bullet was remade with a thinner jacket in order to promote expansion and upset at longer ranges. This 200-grain .338" projectile is able to impart significantly more energy than the 160 gr projectile used in the .308 Marlin Express, despite similar muzzle velocities. Furthermore, the projectile's high ballistic coefficient allows the .338 Marlin Express to maintain velocity to greater distances than big bore lever cartridges such as .45-70, .444 Marlin, or even the high performance .450 Marlin. Although the heavy bullet weight of these cartridges allow them more muzzle energy, the ballistic advantage of the .338 Marlin Express's projectile begins to show beyond 100 yards. After that point the .338 Marlin Express's projectile retains more energy than even the .450 Marlin. Like the .308 Marlin Express, the .338 Marlin Express was designed to be a relatively flat shooting cartridge, taking advantage of the bullets Hornady designed for the rounds. Its trajectory is similar to the .30-06 Springfield. [4] Since the acquisition of Marlin by Ruger, [5] regular production of .338 Marlin Express ammunition by Hornady has ceased.[ citation needed ]

The .338 Marlin Express has a larger diameter than its .308 companion.

The .338 Marlin Express was designed to produce performance similar to the .30-06 Springfield. This would give lever-action hunters improved performance over their .30-30 Winchester rounds. The table below shows how the rounds compare. Reloading data for 200-grain (13 g) bullets for some of the cartridges is not available. Extensive loading data for the .338 Marlin Express is not yet available. The powder used in the Hornady loading is also not yet commercially available as of Feb '09. This round was designed with an elastomer tip, so that the .338 projectile would be safe for use in the tubular magazines of lever-action rifles. Traditional spitzer bullets are not compatible with the tubular magazines. This is due to the danger of the hard, pointed bullet-tip igniting the primer of the round in front of it under recoil impulse. The softer tip eliminates the hazards of stacking pointed rounds end to end in a tubular magazine.[ citation needed ]

The .30-06 Springfield cartridge, 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. In the cartridge's name, ".30" refers to the nominal caliber of the bullet in inches; "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03 Springfield, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. The cartridge remains a very popular sporting round, with ammunition produced by all major manufacturers.

The .22 Winchester Magnum Rimfire, also known as the .22 WMR, .22 Magnum, .22 WMRF, .22 MRF, or .22 Mag, is a rimfire cartridge. Originally loaded with a bullet weight of 40 grains (2.6 g) delivering velocities in the 2,000 feet per second (610 m/s) range from a rifle barrel, .22 WMR is now loaded with bullet weights ranging from 50 grains (3.2 g) at 1,530 feet per second (470 m/s) to 30 grains (1.9 g) at 2,200 feet per second (670 m/s).

<span class="mw-page-title-main">.243 Winchester</span> Rifle cartridge

The .243 Winchester (6×52mm) is a popular sporting rifle cartridge. Developed as a versatile short action cartridge to hunt both medium game and small game alike, it "took whitetail hunting by storm" when introduced in 1955, and remains one of the most popular whitetail deer cartridges. It is also commonly used for harvesting blacktail deer, pronghorns and mule deer with heavier rounds, and is equally suited to varmint hunting with lighter rounds. The .243 is based on a necked down .308 Winchester, introduced only three years earlier. Expanding monolithic copper bullets of approximately 80 to 85 grains or traditional lead rounds of 90 to 105 grains with controlled expansion designs are best suited for hunting medium game, while lighter rounds are intended for varmints.

<span class="mw-page-title-main">.30-40 Krag</span> First cartridge adopted by the US Army that was designed for smokeless powder.

The .30-40 Krag, also known as the .30 U.S. and .30 Army, was a rifle cartridge developed in the early 1890s to provide the U.S. armed forces with a smokeless powder cartridge suited for use with modern small-bore repeating rifles to be selected in the 1892 small arm trials. Since the cartridge it was replacing was the .45-70 Government, the new cartridge was considered small-bore at the time. The rifle ultimately selected for use by the Army was the Krag–Jørgensen, formally adopted as the M1892 Springfield. The cartridge was also used in the M1893, M1895, M1897, and M1900 Gatling guns.

Commonly loaded with a 17 grain projectile, it can deliver muzzle velocities in excess of 775 m/s.

<span class="mw-page-title-main">.30-30 Winchester</span> Rifle cartridge designed by the Winchester Repeating Arms Company

The .30-30 Winchester / 7.8x51mmR cartridge was first marketed for the Winchester Model 1894 lever-action rifle in 1895. The .30-30, as it is most commonly known, along with the .25-35 Winchester, was offered that year as the United States' first small-bore sporting rifle cartridges designed for smokeless powder. Since its introduction, it has been utilized alongside the development of flatter shooting cartridges, most prominently those derived from designs subsidized by interest in military expenditures. The .30-30 has remained in widespread use almost entirely because of reliable effectiveness in civilian applications, and has put food on the table for millions of people in hunting situations.

The .300 Winchester Magnum is a belted, bottlenecked magnum rifle cartridge that was introduced by the Winchester Repeating Arms Company in 1963. The .300 Winchester Magnum is a magnum cartridge designed to fit in a standard rifle action. It is based on the .375 H&H Magnum, which has been blown out, shortened, and necked down to accept a .30 caliber (7.62 mm) bullet.

<span class="mw-page-title-main">.444 Marlin</span> Rifle cartridge

The .444 Marlin (10.9×57mmR) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms. It was designed to fill the gap left when the older .45-70 cartridge was not available in new lever-action rifles; at the time it was the largest lever-action cartridge available. The .444 resembles a lengthened .44 Magnum and provides a significant increase in velocity. It is usually used in the Marlin 444 lever-action rifle. Currently, Marlin, now owned by Ruger Firearms, does not offer the .444 chambering in any of their rifles. It remains to be seen if they will bring the chambering back into production.

<span class="mw-page-title-main">.338 Winchester Magnum</span> Rifle cartridge

The .338 Winchester Magnum is a .338 in (8.6 mm) caliber, belted, rimless, bottlenecked cartridge introduced in 1958 by Winchester Repeating Arms. It is based on the blown-out, shortened .375 H&H Magnum. The .338 in (8.6 mm) is the caliber at which medium-bore cartridges are considered to begin. The .338 Winchester Magnum is the first choice among professional brown bear guides in Alaska to back up clients where a powerful stopping caliber is required on charging bears. It is also the most popular medium-bore cartridge in North America and has the most widely available choice in rifles among medium bore rifles. The action length is the same as a .30-06, and most major rifle manufacturers in the United States chamber rifles for the cartridge including the semi-automatic Browning BAR Mk II Safari, making it a very powerful combination against charging dangerous game. The cartridge was intended for larger North American big-game species and has found use as for the hunting of thin-skinned African plains-game species.
