Questions & Answers
Will this cycle an AR or AK or is it made just for bolt actions.

it depends on your AK, my zpap m70 was slightly undergassed and could not fully cycle with a dead air wolverine on the end of the barrel. i resolved this by adding a 20 dollar kns reduced power recoil spring and it cycles perfeclty, i feel lile if i had 500 rounds to burn through the original spring it might be able to cycle the subsonics but it was all new in box

Hornady® Subsonic Ammunition — designed for accuracy and performance below the speed of sound — now comes in both rifle and handgun loads.image

Subsonic Handgun utilizes tried-and-true XTP® bullets that expand reliably at subsonic velocities. The Sub-X bullet used in Subsonic Rifle features a lead core. Long grooves in its gilding metal jacket combine with the bullet’s flat profile and the patented Flex Tip® insert within its hollowpoint cavity to help it expand reliably at low velocities.

Powders are selected for optimal performance and consistency from lot to lot.

PROVEN PERFORMANCE

Performance of 300 Blackout Subsonic meets or exceeds FBI Protocol terminal ballistic test requirements. The XTP® bullet in Subsonic Handgun has built a world-class reputation for accuracy and stopping power.

SILENT AND STEALTHY

Hornady® Subsonic Ammunition doesn’t have the loud report of a supersonic round, and paired with a suppressor, it’s even quieter. Unique powders optimized for subsonic use result in a low flash signature, ideal for either suppressed or unsuppressed performance.

HIGH-QUALITY COMPONENTS

With high-quality cartridge cases and primers, Subsonic Ammunition offers the performance and accuracy shooters have come to expect from Hornady.
