Just finished up the testing of the 223 Speer Gold Dot 64gr soft point round. Here's a summary of the conditions and results. Test conditions: -16'' PSA mid-length chrome lined barrel -70 degrees -300 feet above sea level -Test rounds fired from 7 feet -FBI spec Clear Ballistics gel block (more on this below) -4 layers of denim Results: -2,753 fps average velocity -1076 ft/lbs energy -18.5'' penetration -Maximum expansion measurement: 0.48'' -Minimum expansion measurement: 0.35'' -Retained weight: 54 grains The manufacture of the gel block, Clear Ballistics, claims their gel meets FBI specs for testing. I calibrate my gel per their specs prior to testing and use 4 layers of denim per IWBA protocol. However, by no means am I saying this test is a substitute for the great work industry professionals like Dr. Roberts and others do. I'm just a shooter that likes to learn about the products I use. Here's the video showing the test, the permanent cavity, and a discussion of the results: [ame]http://youtu.be/KYZ7sYAD_sM[/ame] Questions? Comments? Wanna kill these ads? We can help!
