The .350 Legend typically uses bullets with a caliber of .355 inches (9mm), which is a common caliber for handgun ammunition. This allows for the use of a wide range of bullet types.
The cartridge is designed to deliver good stopping power and accuracy within a certain range, making it suitable for medium-sized game hunting.
The ballistics of the .350 Legend cartridge can vary depending on the load and bullet used. However, it generally offers moderate recoil and good terminal performance at close to medium ranges.
It’s known for having relatively low recoil compared to some other hunting cartridges, making it more accessible to shooters who may not be comfortable with heavier recoil.
4. Ammunition Types
Ammunition for the .350 Legend is available in various bullet types, including soft point, hollow point, and ballistic tip designs. This allows hunters to choose ammunition that suits their specific needs, whether they’re aiming for controlled expansion, deep penetration, or long-range accuracy.
The primary use of the .350 Legend is hunting, particularly for medium-sized game like deer. It’s designed to offer sufficient energy and expansion for clean and ethical kills within a certain effective hunting range.
However, its range is limited compared to some other cartridges, so it’s important for hunters to be aware of their shooting distances.
6. Legal Considerations
One of the main reasons the .350 Legend was developed was to comply with hunting regulations in certain states that require the use of straight-walled cartridges. These regulations are often in place to promote safety and ethical hunting practices.
Firearms chambered in .350 Legend are available from various manufacturers. These include bolt-action rifles, single-shot rifles, and even some semi-automatic rifles. Before purchasing a firearm for this caliber, ensure that it’s legal to use for hunting in your state or region.
Something about .300 Blackout Ammo
.300 Blackout, also known as .300 AAC Blackout or 7.62x35mm, is a relatively new and versatile rifle cartridge designed for use in the AR-15 platform.
It was developed by Advanced Armament Corporation (AAC) with the intention of providing a more effective and flexible alternative to the 5.56x45mm NATO cartridge, especially in short-barreled rifles and suppressed firearms.
Here’s some information about .300 Blackout ammo:
1. Origin and Purpose
.300 Blackout was introduced in 2011 as a response to the limitations of the 5.56mm cartridge in short-barreled rifles and suppressed weapons.
The goal was to create a cartridge that could be fired in standard AR-15 rifles with minimal modifications, while offering improved performance in terms of bullet energy, stopping power, and terminal ballistics.
One of the key features of .300 Blackout is its compatibility with the standard AR-15 platform.
It uses the same magazines and bolt carrier groups as the 5.56mm, requiring only a barrel swap to convert a rifle chambered in 5.56mm to .300 Blackout.
This makes it a popular choice for those who want to maximize the utility of their AR-15 while benefiting from a larger and heavier bullet.
3. Bullet Selection
.300 Blackout ammo is available in various bullet weights and styles, ranging from lightweight varmint loads to heavy subsonic rounds.
This versatility allows shooters to tailor their ammunition choice to the intended purpose, whether it’s home defense, target shooting, hunting, or suppressed shooting.
4. Subsonic and Suppressed Shooting
One of the standout features of .300 Blackout is its ability to be effectively used with subsonic ammunition when paired with a suppressor.
Subsonic rounds, which typically use heavier bullets and travel at slower speeds, greatly reduce the noise produced by the gunshot, making it ideal for stealthy shooting applications.
The .300 Blackout cartridge offers better ballistics than the 5.56mm at shorter ranges, especially when firing heavier bullets. It delivers more energy on target and has better terminal ballistics, making it well-suited for short-barreled rifles and home defense scenarios.
6. Ammunition Types
.300 Blackout ammunition is broadly categorized into two types:
Supersonic: These rounds use lighter bullets and are typically used for hunting and general shooting. They achieve higher velocities and have flatter trajectories.
Subsonic: Subsonic rounds are designed for suppressed shooting. They use heavier bullets to maintain energy and are loaded to travel at subsonic speeds, reducing the sonic crack associated with supersonic bullets.
While .300 Blackout ammo might not be as widely available as more established cartridges like 5.56mm or .308, it has gained popularity and its availability has increased over the years.
Major ammunition manufacturers produce a variety of loads for different purposes.

It is common to measure cross-sectional density (SD) by comparing how well a bullet penetrates a target. The higher the number, the more likely the bullet will knock down the prey by puncturing the skin, tendons, or bones.
Besides, the expansion and velocity factors also create a certain amount of damage. Despite the different weights, the 300 Blackout has a higher cross-sectional density and better penetration than its rivals.
350 Legend has a unique sight design for hunting deer even at long range.
But, it doesn’t mean 300 Blackouts are less effective. This bullet can work very well at close range with wild boar.
With varmint, 300 Blackout has low recoil and is lighter, so it has an advantage over 350 Legend.
Both are capable of firing subsonic projectiles. But experts do not recommend using these 2 for hunting because of their brutality.
The suppressor is responsible for reducing the sound of gunpowder igniting when bullets are fired.
Rifle cartridges can fire at supersonic speeds more fabulous than 1125 fps.
The suppressor of the 300 Blackout is slightly superior to that of the 350 Legend. Specifically, with 300, you can use full powdered burin to create a continuous firing force with high noise immunity.
In the other version, the poor soundproofing makes it impossible for you to fire many bullets in a short time. Its annoying sounds and radiant heat are challenging to handle.
The 300 Blackout is generally a better priority for self-defense due to its suitability for CQB applications. However, 350 Legend can also be available for home defense. Its drawback is that it cannot fit into standard AR-15 boxes.
300 Blackout is a superior self-defense option when operating with a full 30-round magazine and low recoil.
350 Legend was released recently, so users have fewer options compared to 300 Blackout. Only 3 manufacturers offer 350s, Winchester, Hornady, and Federal, while almost every manufacturer produces and supplies 300 Blackouts.
However, the price of the two has almost no difference. You’ll pay more than $1 for each shot of the same size.
Pros and Cons
350 Legend Vs 300 Blackout: Which One Is Better?
Both are products that are good enough for you to handle different goals.
If you’re looking for ammunition capable of firing at a wide range of up to 250 yards, the 350 Legend is a great choice. Its recoil is also not too significant, which may be available in many states, including Michigan and Ohio.
The 300 Blackout will be the ideal choice when you need to hunt at close range.
The outstanding advantages of this design are low recoil and effective cartridges with 30 rounds, allowing supersonic and subsonic bullets to be fired.
