This difference stems from the case design and the types of bullets each cartridge is optimized to use.
The 300 HAM’R, with its higher case capacity, can push heavier bullets at higher velocities, resulting in flatter trajectories and greater energy downrange. This makes it a more effective choice for longer-range shooting and hunting applications where maximum energy transfer is desired. The 300 Blackout, on the other hand, is designed to stabilize heavier, slower-moving bullets for optimal suppressed performance. This comes at the cost of some ballistic performance compared to the 300 HAM’R when using supersonic ammunition.
Supersonic Performance
In terms of supersonic performance, the 300 HAM’R typically exhibits higher velocities and flatter trajectories than the 300 Blackout. For example, a typical 125-grain bullet fired from a 300 HAM’R can achieve velocities of around 2500-2600 fps, while a similar bullet fired from a 300 Blackout might only reach 2200-2300 fps. This difference in velocity translates to a significant advantage in terms of range and energy.
Subsonic Performance
The 300 Blackout is specifically designed for optimal subsonic performance, making it the clear winner in this category. Its shorter case and faster twist rate barrels allow it to effectively stabilize heavy, slow-moving bullets, resulting in excellent accuracy and minimal noise when used with a suppressor. The 300 HAM’R can also fire subsonic rounds, but it is not optimized for this purpose, and its performance may not be as consistent or accurate as the 300 Blackout.
