Speer Gold Dot 64gr Soft Point Ammo Test



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 Gel 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.
