Hornady A-MAX 208gr Subsonic

Hornady 300 AAC Blackout 208-grain A-MAX Subsonic leverages one of the most respected match bullet designs ever produced for subsonic precision shooting. The A-MAX bullet, renowned for its exceptional accuracy in long-range competition shooting, features a polymer tip and boat tail design that delivers an outstanding ballistic coefficient for its weight class. While the A-MAX was not designed for terminal expansion at subsonic velocities, its match-grade accuracy makes it the preferred choice for shooters who prioritize precision in suppressed applications.

At 1,020 fps from a 16-inch barrel with 480 ft-lbs of muzzle energy, the 208-grain A-MAX remains comfortably subsonic throughout its flight envelope, eliminating the supersonic crack that would compromise suppressor effectiveness. The heavy 208-grain bullet weight requires a 1:7 or 1:8 twist barrel for proper stabilization, but when paired with an appropriate barrel, delivers exceptional group sizes that rival dedicated precision rifle ammunition. The consistent velocities from Hornady's quality control processes ensure minimal vertical dispersion, which is critical for subsonic precision where small velocity variations can significantly affect point of impact.

For shooters who use their suppressed .300 Blackout rifles primarily for range work, training, and precision shooting rather than hunting or defense, the 208gr A-MAX provides match-grade accuracy at an accessible price point. The brass cases are reloadable, which adds value for precision shooters who develop custom loads for their specific barrels. While those needing terminal performance should look to expanding subsonic designs like Hornady's own Sub-X, the A-MAX fills the niche of affordable, exceptionally accurate subsonic ammunition for suppressed precision applications.
