Frequently Asked Questions

Why does subsonic ammunition matter for suppressor use? A suppressor only quiets the muzzle blast; a bullet traveling faster than sound still produces a sharp sonic crack, so subsonic loads like this one are needed for genuinely quiet shooting.

Does subsonic loading hurt the XTP’s expansion? Hornady tunes the Subsonic line to still drive the XTP hard enough for reliable expansion despite the reduced velocity.
