The DoubleTap Colt Defense line brings a straightforward approach to .300 Blackout ammunition. This load pairs a 125-grain Sierra Tipped MatchKing projectile with consistent velocities that hit 2400 fps from the muzzle. You get 1599 foot-pounds of energy at the point of firing, which translates to solid on-target performance across different shooting distances.
The Sierra TMK bullet in this load is engineered with a polymer tip that improves its ballistic coefficient—meaning the round maintains velocity and energy better as it travels downrange. This design also supports controlled expansion on impact. The hollow point construction is built for terminal effect without over-penetration, which gives you a predictable performance envelope for defensive scenarios.
One of the main selling points here is compatibility. Whether your rifle runs a suppressor or stays unsuppressed, these rounds function reliably. The velocity profile works well across different barrel lengths too. The 125-grain weight is a natural sweet spot for the .300 Blackout cartridge—light enough for flat trajectories and consistent cycling, but substantial enough to deliver genuine impact.
Double Tap built its reputation on quality control and precision manufacturing, and these rounds reflect that approach. You get 20 rounds per box loaded into new brass with proper primer seating and powder charge consistency. The attention to detail shows in the accuracy potential and shot-to-shot reliability that users have reported across various platforms.
Yes. These rounds are loaded to 2400 fps specifically to function reliably whether you're running a suppressor or shooting unsuppressed. The velocity is consistent enough to ensure proper bolt cycling and reliable feeding across different barrel lengths and platform configurations.
The Sierra Tipped MatchKing uses a polymer tip that improves ballistic coefficient and initiates controlled expansion on impact. This design gives you better downrange performance and more predictable terminal effect compared to traditional hollow point designs. The tip also helps with feeding reliability in AR-platform rifles.
DoubleTap positioned the Colt Defense load for defensive applications, but the accuracy and consistency of the load make it equally capable at the range. The Sierra TMK projectile is accurate at distance, and the 125-grain weight keeps recoil manageable for follow-up shots in either context.
Yes. The cartridges use new boxer-primed brass that's compatible with standard reloading equipment. The brass quality from Double Tap is consistent, which is helpful if you plan to reload multiple times.
