## Understanding the 300 HAM’R
The 300 HAM’R, developed by Bill Wilson of Wilson Combat, is designed to maximize the AR-15 platform’s potential within its dimensional constraints. It’s chambered for .30 caliber bullets and optimized for supersonic performance, offering a significant increase in energy and range compared to the 300 Blackout in many scenarios. The development of the 300 HAM’R aimed to address perceived shortcomings of the 300 Blackout, particularly in hunting applications and longer-range shooting where a flatter trajectory and higher retained energy are desirable.
### Key Features of the 300 HAM’R
* **Optimized for Supersonic Performance:** The 300 HAM’R is designed to excel with supersonic ammunition, delivering higher velocities and flatter trajectories than the 300 Blackout in comparable barrel lengths.
* **Increased Energy and Range:** The cartridge offers a substantial increase in muzzle energy and effective range, making it suitable for hunting medium-sized game and engaging targets at extended distances.
* **AR-15 Compatibility:** The 300 HAM’R is designed to function reliably in standard AR-15 platforms with only a barrel change, making it a relatively simple conversion.
* **.30 Caliber Bullet Selection:** The cartridge utilizes a wide range of readily available .30 caliber bullets, providing flexibility in load selection and performance characteristics.
### The Purpose-Built Hunting Cartridge
The 300 HAM’R was explicitly developed as a hunting cartridge. Its higher velocity and energy translate to better terminal performance on game animals, making it a more ethical choice for hunting deer, hogs, and other medium-sized species. Bill Wilson’s personal hunting experiences heavily influenced the design, focusing on practical performance in real-world hunting scenarios.
## Exploring the 300 Blackout
The 300 Blackout (7.62x35mm) was developed by Advanced Armament Corporation (AAC) in collaboration with Remington Defense. Its primary goal was to create a cartridge that offered similar ballistics to the 7.62x39mm AK-47 round but could function reliably in the AR-15 platform using standard magazines and bolt carriers. The 300 Blackout quickly gained popularity due to its versatility in both supersonic and subsonic applications, making it a favorite among tactical shooters and those seeking suppressed performance.
### Core Attributes of the 300 Blackout
* **Supersonic and Subsonic Versatility:** The 300 Blackout excels in both supersonic and subsonic roles, offering a wide range of ammunition options for various applications.
* **Excellent Suppressed Performance:** The cartridge is particularly well-suited for use with suppressors, providing significantly reduced noise levels when paired with subsonic ammunition.
* **AR-15 Compatibility:** Like the 300 HAM’R, the 300 Blackout is designed to function reliably in standard AR-15 platforms with only a barrel change.
* **Magazine Compatibility:** The 300 Blackout can utilize standard AR-15 magazines, although some specialized magazines are available for improved feeding reliability with certain bullet profiles.
### A Cartridge Designed for Adaptability
The 300 Blackout’s design philosophy centered on adaptability. Its ability to effectively utilize both supersonic and subsonic ammunition makes it a versatile choice for a wide range of applications, from close-quarters combat to hunting and recreational shooting. The cartridge’s popularity has led to a vast selection of commercially available ammunition and reloading components.
## Ballistic Performance: 300 HAM’R vs 300 Blackout
When comparing the ballistic performance of the 300 HAM’R and 300 Blackout, several factors come into play, including bullet weight, velocity, and ballistic coefficient. The 300 HAM’R generally offers higher velocities and flatter trajectories with supersonic ammunition, while the 300 Blackout shines in subsonic applications. Understanding these differences is crucial for selecting the right cartridge for your intended use.
### Supersonic Performance Comparison
In the supersonic realm, the 300 HAM’R typically outperforms the 300 Blackout in terms of velocity and energy. For example, a 125-grain bullet fired from a 16-inch barrel 300 HAM’R can achieve velocities of around 2500 fps, while a similar bullet fired from a 300 Blackout might only reach 2200 fps. This translates to a flatter trajectory, greater effective range, and more significant terminal energy on target.
### Subsonic Performance Analysis
The 300 Blackout truly excels in subsonic applications. Its larger bullet diameter and heavier bullet weights allow it to maintain sufficient energy and momentum, even at low velocities. Subsonic 300 Blackout ammunition is typically loaded with bullets weighing between 200 and 220 grains, providing excellent suppressed performance and reduced noise levels.
The 300 HAM’R can be loaded with subsonic ammunition, but its performance is generally not as optimized as the 300 Blackout. The 300 HAM’R’s case capacity and chamber dimensions are designed for supersonic loads, which means that subsonic loads may not cycle as reliably or offer the same level of accuracy.
## Effective Range: Where Each Cartridge Excels
The effective range of a cartridge is determined by its ability to maintain sufficient velocity and energy to reliably hit and incapacitate a target. The 300 HAM’R’s higher velocities and flatter trajectories generally give it a longer effective range than the 300 Blackout in supersonic applications. However, the 300 Blackout’s subsonic capabilities make it effective at shorter ranges, particularly in situations where noise reduction is paramount.
### 300 HAM’R: Extended Range Capabilities
The 300 HAM’R can effectively engage targets out to 300 yards or more, depending on the specific load and environmental conditions. Its flatter trajectory allows for easier shot placement at longer distances, and its higher retained energy ensures sufficient terminal performance on game animals.
### 300 Blackout: Close-Quarters Dominance
The 300 Blackout is most effective at ranges of 200 yards or less, particularly when using subsonic ammunition. Its heavier bullets provide excellent stopping power at close ranges, and its suppressed performance makes it ideal for tactical applications and hunting in areas where noise is a concern.
## Common Applications: Matching the Cartridge to the Task
The 300 HAM’R and 300 Blackout are suited for different applications based on their respective strengths. The 300 HAM’R is primarily a hunting cartridge, while the 300 Blackout is more versatile, serving well in tactical, hunting, and recreational shooting roles.
### Hunting with the 300 HAM’R
The 300 HAM’R is an excellent choice for hunting medium-sized game, such as deer and hogs. Its higher velocity and energy provide better terminal performance than the 300 Blackout, making it a more ethical choice for hunting. Many hunters report clean, quick kills with the 300 HAM’R, attributing its effectiveness to its optimized ballistics and terminal performance.
### Tactical and Suppressed Applications with the 300 Blackout
The 300 Blackout is a popular choice among tactical shooters due to its versatility and suppressed performance. Its subsonic capabilities make it ideal for close-quarters combat and stealth operations, while its supersonic loads provide sufficient power for longer-range engagements. Law enforcement and military units often utilize the 300 Blackout in situations where noise reduction is critical.
