Federal HST 124gr +P 9MM Various Barrel Lengths Gel Test 9x19
This video from Buckeye Ballistics provides a comprehensive gel test of Federal HST 124gr +P 9mm ammunition across various barrel lengths (3.3" to 10.5"). The expert analysis highlights how barrel length significantly impacts velocity and bullet expansion, with longer barrels generally yielding higher velocities and more dramatic "flowering" of the projectile. The test uses calibrated ballistic gelatin to simulate tissue and offers valuable insights for selecting ammunition based on intended firearm platform.
