Exploring the .450 Marlin: A Modern Magnum
The .450 Marlin, introduced in 2000 by Marlin Firearms and Hornady, was designed to offer magnum performance in a lever-action platform. It addresses some perceived limitations of the .45-70, particularly its potential for being chambered in weaker, older rifles. The .450 Marlin features a belted case, a design element borrowed from magnum rifle cartridges, which prevents it from being chambered in rifles not designed for its higher pressures. This added safety measure ensures that the .450 Marlin is only used in modern, strong lever-action rifles.
The .450 Marlin delivers significantly more power than standard .45-70 loads, offering flatter trajectories and greater downrange energy. This makes it a suitable choice for hunters seeking extended range and increased stopping power on large game. However, this increased performance comes at a cost: the .450 Marlin generates significantly more recoil than the .45-70, which can be a deterrent for some shooters. The cartridge is primarily chambered in Marlin’s lever-action rifles, limiting rifle choices compared to the .45-70.
Key Characteristics of the .450 Marlin
- History: Introduced in 2000 by Marlin Firearms and Hornady.
- Bullet Diameter: .458 inches (same as .45-70).
- Case Type: Straight-walled, belted magnum.
- Typical Bullet Weights: 325 to 350 grains.
- Effective Range: Capable of effective shots beyond 200 yards, with flatter trajectories than the .45-70.
Ballistics and Performance: A Head-to-Head Comparison
When comparing the ballistics of the .45-70 and .450 Marlin, it’s crucial to consider specific loads. Generally, the .450 Marlin offers higher velocities and flatter trajectories. For example, a typical .450 Marlin load might push a 325-grain bullet at around 2,200 fps, while a comparable .45-70 load might achieve around 1,800-2,000 fps. This difference in velocity translates to a flatter trajectory and greater energy on target at longer ranges.
However, the .45-70’s versatility allows for a wide range of bullet weights and velocities. Handloaders can tailor the cartridge to match or even exceed the performance of some .450 Marlin loads. Furthermore, the .45-70’s heavier bullet options (up to 500 grains) can provide superior penetration on large, dangerous game at close ranges. The choice ultimately depends on the intended application and the shooter’s preference.
Ballistic Data (Approximate):
| Cartridge | Bullet Weight (grains) | Muzzle Velocity (fps) | Muzzle Energy (ft-lbs) | 100 Yard Energy (ft-lbs) |
|---|---|---|---|---|
| .45-70 | 325 | 2,000 | 2,886 | 2,200 |
| .45-70 (Heavy Load) | 405 | 1,800 | 2,914 | 2,400 |
| .450 Marlin | 325 | 2,200 | 3,500 | 2,700 |
Recoil: A Matter of Tolerance
Recoil is a significant factor to consider when choosing between the .45-70 and .450 Marlin. The .450 Marlin, with its higher velocities and heavier bullet weights, generates significantly more recoil than most .45-70 loads. This can be a deterrent for recoil-sensitive shooters or those who plan to shoot frequently. The .45-70, with its wider range of available loads, allows shooters to choose options with manageable recoil levels.
Experienced shooters who are comfortable with heavy recoil may appreciate the .450 Marlin’s added power. However, for most hunters, the .45-70 offers a more comfortable and controllable shooting experience. The ability to practice more frequently and maintain accuracy is crucial, especially when hunting dangerous game. Factors like rifle weight, stock design, and recoil pads can also influence perceived recoil.
Rifle Availability and Options
Rifle availability is another critical consideration. The .45-70 Government has been chambered in a wide variety of rifles over the years, including lever-actions, single-shots, and even some bolt-actions. This widespread availability provides shooters with a greater range of options in terms of rifle style, price, and features. Marlin, Henry, and Winchester are popular brands offering .45-70 rifles.
The .450 Marlin, on the other hand, is primarily chambered in Marlin lever-action rifles. This limited availability restricts choices for shooters who prefer other rifle brands or styles. While Marlin rifles are known for their quality and reliability, the lack of alternative options may be a deciding factor for some.
Hunting Applications: Matching the Cartridge to the Game
Both the .45-70 and .450 Marlin are capable of taking down a wide range of game, but their strengths lie in different areas. The .45-70 is an excellent choice for hunting deer, bear, and elk at moderate ranges, particularly in wooded areas where shots are typically closer. Its heavier bullet options provide excellent penetration on large, thick-skinned animals.
The .450 Marlin excels in situations where longer shots are anticipated or where maximum stopping power is required.
