Simple penetration and expansion test of the Speer Gold Dot .380 ACP 90 gr GDHP, using a diluted form of SIM-TEST Ballistic Testing Media. This format is comparable to calibrated ballistic gel, and includes four layers of denim. Video includes brief overview of the cartridge, recoil shots, and one shot test. Post-shot evaluation shows bullet path through the block, average diameter, and retained weight. Test gun was a Bersa Thunder 380 Plus, 3.5" barrel. Advertised muzzle velocity is 1040 fps, my 5-shot average was 980 fps.
