350 Legend vs. 450 Bushmaster: Which Straight-Wall Cartridge Is Better?
The 350 Legend vs 450 Bushmaster debate comes down to two very different ways of getting more performance from a straight-wall hunting cartridge. The 350 Legend emphasizes manageable recoil, efficient ballistics, and affordable ammunition, while the 450 Bushmaster delivers a much larger projectile and substantially greater muzzle energy.
Both cartridges are available in AR-pattern and bolt-action platforms and are popular among hunters pursuing deer and hogs. The better choice depends on your expected hunting distance, recoil tolerance, rifle configuration, ammunition budget, and current state regulations.
350 Legend vs. 450 Bushmaster: The Quick Answer
The 350 Legend is generally the more practical cartridge for hunters who prioritize lower recoil, ammunition cost, and a flatter trajectory at moderate distances. The 450 Bushmaster delivers substantially more muzzle energy and a larger projectile, making it attractive when maximum short- to medium-range terminal performance is the priority.
| Category | Winner | Why |
|---|---|---|
| Recoil | 350 Legend | Significantly lower recoil |
| Muzzle energy | 450 Bushmaster | Much heavier projectile and greater energy |
| Trajectory | 350 Legend | Generally flatter with common hunting loads |
| Ammunition cost | 350 Legend | Broader, more economical market |
| Rifle selection | 350 Legend | Extensive commercial support |
| Close-range hunting power | 450 Bushmaster | Larger projectile and higher energy |
| Extended practical range | 350 Legend | Flatter trajectory with common loads |
| Reloading | 350 Legend | Established component ecosystem |
| Compact AR-platform hunting | Draw | Both have strong options |
The category score is less important than matching the cartridge to the job. For many deer hunters, the 350 Legend’s combination of low recoil and practical range is enough. Hunters who want more projectile mass and energy at close and moderate distances may prefer the 450 Bushmaster.
Cartridge Specs
Both cartridges are straight-wall rifle cartridges, but their dimensions and performance are very different.
The 350 Legend uses a .355-.357-inch-class projectile and a relatively compact case. The 450 Bushmaster uses a much larger .452-inch bullet and significantly greater case capacity.
SAAMI lists both cartridges at a maximum average pressure of 55,000 psi for 350 Legend and 38,500 psi for .450 Bushmaster. (saami.org)
| Specification | 350 Legend | 450 Bushmaster |
| Bullet diameter | .355-.357″ class | .452″ |
| Case length | 1.71″ | 1.70″ |
| Overall length | Approximately 2.25″ | Approximately 2.26″ |
| SAAMI MAP | 55,000 psi | 38,500 psi |
| Typical bullet weight | 145–180 gr | 200–300+ gr |
| Primary use | Deer, hogs, general hunting | Deer, hogs, larger game at suitable ranges |
One important correction: the two cartridges are not interchangeable, and their components are not simply swapped between AR-15 builds.
Recoil: Winner — 350 Legend
The biggest practical advantage of the 350 Legend recoil profile is how manageable it is in a hunting rifle.
The 450 Bushmaster fires significantly heavier bullets and generally produces substantially more recoil. In a similarly weighted rifle, many shooters will notice the difference immediately.
Recoil varies according to rifle weight, ammunition, bullet weight, muzzle velocity, stock geometry, and muzzle devices. That means there is no single recoil figure that applies to every rifle.
Still, the overall pattern is clear: 350 Legend is considerably easier on the shoulder than 450 Bushmaster.
That matters for hunters who practice extensively, younger or recoil-sensitive shooters, and anyone who expects to fire multiple rounds during a hunt.
Trajectory: Winner — 350 Legend
The 350 Legend trajectory is generally flatter than typical 450 Bushmaster hunting loads because it fires a lighter projectile at a higher velocity.
That difference can make the 350 Legend easier to use at moderate hunting distances, particularly when range estimation is less precise.
The 450 Bushmaster’s heavier bullet and lower velocity result in more pronounced drop as distance increases.
Neither cartridge is a true long-range rifle cartridge, however. Their real-world usefulness depends heavily on the selected ammunition and intended game.
Rather than assigning a universal effective range, hunters should examine the manufacturer’s trajectory and terminal-performance data for the specific load.
Muzzle Velocity and Energy: Winner — 450 Bushmaster
This is where the 450 Bushmaster has the most obvious advantage.
Its larger bullet and heavier projectile weights allow it to produce substantially greater muzzle energy than typical 350 Legend loads.
The 350 Legend takes a different approach: higher velocity with a smaller projectile produces a flatter trajectory and more manageable recoil.
The 450 Bushmaster therefore gives up some trajectory and recoil comfort in exchange for substantially greater projectile mass and energy.
Ballistic Coefficient
Neither cartridge was designed primarily for extreme long-range shooting, so ballistic coefficient should not be overemphasized.
The 350 Legend uses smaller-diameter bullets that can achieve useful BC values despite their relatively short length. The 450 Bushmaster fires much wider projectiles, which generally face greater aerodynamic drag.
The exact BC depends heavily on projectile design. Comparing cartridge-wide averages can therefore be misleading.
For normal hunting distances, bullet construction and the specific load are usually more important than small differences in BC.
350 Legend vs. 450 Bushmaster for Deer Hunting
For whitetail hunting, both cartridges can be effective with appropriate hunting ammunition where legal.
The 350 Legend is particularly attractive because its recoil is manageable and its trajectory is relatively flat for a straight-wall cartridge.
The 450 Bushmaster delivers considerably more energy and a larger projectile, which can make it appealing for hunters who favor maximum close- to moderate-range power.
Terrain matters too. A hunter working dense timber may rarely need the additional ballistic capability of a larger cartridge. In more open terrain, the 350 Legend’s flatter trajectory can be useful.
The best choice is therefore not determined by cartridge size alone.
350 Legend vs. 450 Bushmaster for Hog Hunting
Both cartridges are popular for feral hogs, but they offer different advantages.
The 350 Legend gives hunters relatively low recoil and quick recovery between shots.
The 450 Bushmaster provides a much heavier projectile and greater muzzle energy, making it attractive for hunters who place a premium on close-range terminal performance.
The appropriate load matters enormously. Hunters should select ammunition specifically designed for the intended game rather than relying solely on bullet weight.
Effective Range
One of the weakest aspects of the original article is assigning fixed ranges such as “200 yards” for 350 Legend and “300 yards” for 450 Bushmaster.
There is no universal effective range for a cartridge.
A cartridge can remain physically capable of reaching much farther than the distance at which a particular hunter can ethically and consistently make a shot. Hunting range depends on:
- specific ammunition
- bullet construction
- remaining impact velocity
- firearm accuracy
- range estimation
- wind
- shooter skill
- game size and angle
For most hunters, both cartridges are best viewed as short- to moderate-range hunting cartridges, with the 350 Legend generally providing the flatter trajectory and the 450 Bushmaster providing more energy.
AR-15 Compatibility
Both cartridges are available in AR-platform rifles, but the conversion process is not identical.
The 350 Legend can be built on a standard AR-15 lower, but it requires the appropriate 350 Legend barrel, bolt/bolt head, and magazine configuration.
The 450 Bushmaster also uses an AR-15-based platform but requires a dedicated barrel, bolt, and magazine system designed for the cartridge.
The important point is that neither cartridge should be treated as a simple “barrel-only” conversion without confirming compatibility of the complete upper, bolt, magazine, and other components.
For hunters looking at factory rifles, both cartridges are available from several manufacturers.
Ammo Availability and Cost: Winner — 350 Legend
The 350 Legend ammo market is generally broader and more economical than 450 Bushmaster.
Winchester’s introduction of the 350 Legend helped establish a large commercial market, particularly in states where straight-wall cartridges are popular for deer hunting.
The 450 Bushmaster remains widely available as well, but its larger projectile and generally higher material consumption tend to make ammunition more expensive.
For a hunter who shoots frequently, ammunition cost can become a major consideration.
Rifle Availability: Winner — 350 Legend
The 350 Legend has a strong selection of factory rifles, including AR-pattern rifles and bolt-action hunting rifles.
The 450 Bushmaster is also supported by major manufacturers, particularly for AR-pattern hunting rifles, but the selection is generally narrower.
Both cartridges can be found in compact hunting rifles well suited to woods and brush hunting.
Reloading
Both cartridges have established reloading support.
The 350 Legend benefits from a substantial commercial ecosystem, while the 450 Bushmaster also has readily available brass, bullets, dies, and published load data.
Reloaders should always use current manufacturer-approved components and published data for the exact cartridge and bullet combination.
Do not assume that load data for one straight-wall cartridge can be transferred to another.
350 Legend Ballistics
The 350 Legend’s defining ballistic characteristic is the balance between velocity and projectile weight.
Factory loads commonly fall around the 145- to 180-grain range, giving hunters a choice between relatively flat trajectory and heavier hunting projectiles.
That combination gives the cartridge useful performance for deer and hog hunting while keeping recoil relatively modest.
450 Bushmaster Ballistics
The 450 Bushmaster takes a different approach.
Factory ammunition commonly uses bullets from approximately 200 grains through 300 grains or more. These heavier projectiles can produce substantial muzzle energy while maintaining useful hunting performance at moderate distances.
The trade-off is trajectory and recoil.
A hunter choosing 450 Bushmaster should therefore be comfortable with the cartridge’s recoil and understand the trajectory of the exact load being used.
Straight-Wall Cartridge Hunting Regulations
Straight-wall cartridge rules are state-specific and can change.
Ohio, Michigan, Indiana, Iowa, Illinois, and Pennsylvania have all had regulations involving straight-wall cartridges, but the precise requirements differ by state, hunting zone, firearm, season, and cartridge specifications.
Do not rely on a generic list of states. Hunters should check the current regulations from their state wildlife agency before purchasing ammunition or hunting.
