At Halworx Ballistics we specialize in terminal performance.

300 Blackout, also known as 300 BLK and 7.62x35mm was designed to offer power similar to the 7.62x39mm Soviet. It’s characterized by its versatility, allowing for it to be loaded to both supersonic and subsonic velocities while still reliably functioning in a semi-auto platform.

In supersonic form with proper hunting class projectiles, the 300 BLK can be an effective hunting cartridge within reasonable distances. It’s well suited as a CQB cartridge because of its versatility and inherently efficient case design, allowing for short barrels which translates to extremely compact weapon systems like PDW’s.  

In subsonic form, the 300 Blk is an excellent home defender delivering 45acp energy levels while staying hearing safe when combined with a sound suppressor. 

If a leap forward in performance was what you were looking for and you don’t mind trading the smaller framed AR15 platform for the larger AR10, then the 8.6 Blackout maybe it for you.

The 8.6 Blk was introduced with an extremely fast 1:3 twist rate which effectively increases terminal performance by initiating rapid expansion resulting in impressive terminal performance. This performance comes at a cost as manufacturers are required to produce a projectile that will withstand the extreme twist rate. This is why 8.6 Blk doesn’t have any traditional bullet designs such as “cup-and-core” bullets in its lineup and is primarily a monolithic or “solid copper only” offering in supersonics.

 If you desire most of the performance of the 8.6 Blk in both supersonic and subsonic offerings but don’t want to give up the AR15’s lightweight and compact versatility, consider the .338 Spectre.

The .338 Spectre is a step-up from the 300 Blk in both supersonic and subsonic offerings. With the ability to shoot a 165gr Maker Rex Expander 1900 fps from a 16”, and a 300gr Maker Rex Subsonic Expander all from the same platform, it effectively increases the energy nearly 20% above the 300 Blk but retains most of the desirable benefits of both the 300 Blk and the 8.6 Blackout. 

If a lightweight and compact bolt-gun in a short action is what you want, go the 8.6 Blk route. The 8.6 Blk will effectively increase terminal performance over the .338 Spectre by 20% in both supersonic and subsonic offerings. If 8.6 Blk is still not enough…we have you covered there too with the .375 Raptor. 

Imagine having the versatility of the previous mentioned cartridges with “big game” performance in mind. 

The .375 Raptor is capable of sending a 400gr expanding projectile at subsonic velocity with 1,000 ft lbs of energy behind it at hearing safe levels, and a 190gr Maker Rex with close to 2,800 ft lbs of energy behind it.
