To get to the heart of the 450 Bushmaster vs 45-70 comparison, let’s dive into the ballistics. Here’s how these cartridges stack up in terms of velocity, energy, and trajectory.

450 Bushmaster Ballistics

The 450 Bushmaster typically fires a .452-inch diameter bullet weighing 250 to 300 grains. A popular load, like the Hornady Black 250-grain FTX, delivers:

  • Muzzle Velocity: ~2,200 feet per second (fps)

  • Muzzle Energy: ~2,700 foot-pounds (ft-lbs)

  • Effective Range: ~200-250 yards

  • Effective Range: ~150-200 yards (modern loads can extend to 300+ yards)

Firearm Platforms: 450 Bushmaster vs 45-70

The type of firearm each cartridge is designed for is a key factor in the 450 Bushmaster vs 45-70 debate. Your choice of platform can significantly impact your shooting experience.

450 Bushmaster Firearms

The 450 Bushmaster shines in the AR-15 platform, offering semi-automatic fire and modularity. Popular rifles include:

  • Bushmaster 450: A dedicated AR-15 upper designed for the cartridge.

  • Ruger American Ranch: A bolt-action option for precision hunters.

  • CMMG Resolute: A high-quality AR-15 for tactical shooters.

Hunting Applications: 450 Bushmaster vs 45-70

Both cartridges are built for hunting, but they excel in different scenarios. Let’s explore how they perform for various game and terrains.

450 Bushmaster for Hunting

The 450 Bushmaster is a go-to choice in states like Michigan and Ohio, where straight-walled cartridges are required for deer hunting. Its strengths include:

  • Versatility: Effective for deer, hogs, and black bear within 200 yards.

  • Low Recoil: Comfortable for younger or recoil-sensitive shooters.

  • Accuracy: Flat trajectory suits brush and open fields.

The semi-automatic capability of the 450 Bushmaster is a game-changer for fast-moving game or multiple targets, giving it an edge in certain hunting scenarios.

45-70 for Hunting

The 45-70 is a beast for big game, with its heavy bullets making it ideal for:

  • Large Game: Perfect for elk, moose, and grizzly bears.

  • Close-Quarters: Unmatched stopping power in heavy cover.

  • Reloading Flexibility: Wide range of bullet weights for custom loads.

The 450 Bushmaster vs 45-70 comparison for hunting favors the 45-70 for dangerous game or hunters who need maximum stopping power at close range.




Recoil and Shootability: 450 Bushmaster vs 45-70

Recoil plays a big role in shootability, especially for long hunting trips or range sessions. Here’s how the cartridges compare:

  • 450 Bushmaster: Produces moderate recoil, similar to a 20-gauge shotgun. Its semi-automatic action absorbs some of the kick, making it easier to handle for extended shooting.

  • 45-70 Government: Delivers stout recoil, especially with heavy 400-500 grain loads. Lever-action rifles transfer more felt recoil to the shooter, which can be tiring.

For shooters prioritizing comfort, the 450 Bushmaster has an advantage. However, modern recoil pads and proper technique can make the 45-70 more manageable.




Ammunition Cost and Availability

Cost and availability are practical considerations when choosing between these cartridges:

  • 450 Bushmaster: Ammo is less common than mainstream cartridges like .308, with brands like Hornady, Winchester, and Remington offering loads at $1.50-$2.50 per round. Its specialized nature makes it pricier.

  • 45-70 Government: Benefits from its long history, with a wide range of loads from Federal, Buffalo Bore, and Garrett. Prices range from $1.00-$3.00 per round, and ammo is more readily available, especially in rural areas.

The 45-70 has a slight edge in availability and cost, particularly for budget-conscious shooters.




Reloading: 450 Bushmaster vs 45-70

For handloaders, both cartridges offer opportunities for customization:

  • 450 Bushmaster: Uses .452-inch pistol bullets, common in .45 ACP and .454 Casull. Its straight-walled case is easy to reload, though load data is less extensive.

  • 45-70 Government: Fires .458-inch bullets with a wide range of weights and types. Its long history provides abundant load data, making it a favorite for reloaders.

The 45-70 has an advantage for handloaders due to its versatility and extensive reloading resources.
