Important Product Information

Actual velocities may vary depending on barrel length, firearm configuration, temperature, and other shooting conditions. Subsonic performance and reliable cycling are firearm-dependent.

Every cartridge undergoes individual chamber-gauge inspection as part of our quality-control process. This inspection verifies dimensional fit but does not guarantee functioning in every firearm.

Use only in appropriately chambered firearms and follow the firearm manufacturer's recommendations.
