Special thanks to rbernie, who sponsored this test in full.
Cartridge : 5.45x39mm 60gr Wolf hollowpoint
Firearm : Romanian AK74 with 16.0" barrel length
Block calibration : 10.3cm @ 584 ft/sec (depths corrected up to point of bullet yawing)
Single shot fired to the center of 10x10x16" ballistic gelatin block. Shot was fired at 10' distance and impacted at 2871 ft/sec. Bullet traveled point-forward to 8.4" (with slight yawing beginning at 3.4" depth). At this point, the bullet turned approximately 90 degrees with respect to its initial line of travel, producing cracks in the gelatin of 3.9" maximum diameter. The bullet experienced minor fragmentation at this point, sending a fragment weighing 3.9gr at a ~45 degree angle for 2.1" (uncorrected) depth and a second fragment of 2.1gr to a 1.3" (uncorrected) penetration. At ~8.6" depth, the bullet veered left of its initial direction of travel at a 40 degree angle. At the rear face of the block, a rectangular hole measuring 1.9" wide by 0.20" high was noted, as well as a golf-ball sized piece of gelatin on the verge of separation from the back of the block.
The polyester bullet arresting material was contained in a black plastic trash bag and placed 1" rearward of the gelatin block. Three slivers of black plastic bag were drawn ~ 3" into the wound channel by the passage of the bullet into the plastic bag. The bullet was recovered at an unknown distance into the polyester bullet arresting box.
