Special thanks to J.K. for sponsoring this test in full and Shadan7 for setting this up, in the initial stages.
Cartridge : 5.7x28mm FN SS195 lead free FMJ (Part # 10700013)
Firearm : FN PS90 rifle (16.1" barrel length) and FN 5.7 handgun (4.8" barrel length), as indicated
Block calibration : 9.1cm @ 591 ft/sec
Shot 1 - Fired by PS90. Impacted at 2157 ft/sec, penetrated nose-forward to 2.1" depth, at which point the bullet tumbled and partially spit the core out of the jacket. Final penetration depth was 7.6" and recovered weight was 28.1gr.
Shot 2 - Fired by 5.7 pistol. Impacted at 1969 ft/sec, penetrated nose-forward to 3.8" depth, at which point the bullet tumbled and spit the core section out of the jacket. The core material penetrated to 7.9" and the maximum penetration depth was 9.7". Bullet recovered at 27.6gr weight.
At this point, the test setup was altered. At the request of the test's sponsor, the potential liability of the tested bullets in the case of an overpenetration of the target in an interior room was assessed. This was accomplished by the cutting of the gelatin block into two 8"x6"x6" blocks, placing one piece at a linear distance of 4" from the face of the FBI 'interior wall' test fixture (two pieces of 0.5" wallboard, on a 2x4 frame), while placing the other block 4" back from the rearmost wallboard panel. This setup is illustrated by the attached photograph of the test setup.
Block calibration for this event was 10.5cm @ 590 ft/sec.
Shot 3 - Fired by PS90. Impacted at 2153 ft/sec, penetrated to 8.0", exited the back of the gelatin block and the jacket section was recovered after through-penetration of both interior wall panels. Bullet fragments did not penetrate the gelatin block. Core section was spit and was not recovered.
Shot 4 - Fired by 5.7 pistol. Impacted at 1983 ft/sec, bullet was not recovered, but by inspection of the wallboard directly behind the block, no part of the bullet penetrated the rearmost drywall panel.
