Firearm : gas-operated semi-automatic with 20" barrel length and 1/10" twist
Cartridge : Federal Classic Hi-Shok 123gr softpoint
Block calibration : All depths corrected (10.9cm at 593 ft/sec)
Single shot impacted the block at 2254 ft/sec, penetrated to 14.0" and was recovered at 0.632" average diameter.
Bullet exhibited significant fragmentation and was recovered at 93.7gr. The primer almost backed out of the primer pocket - the guns owner reasoned that the round was underpressure, due to the groove diameter of his weapon being 0.311", while the ammunition in usage was a true 0.308" bullet.
