I Screwed Up: Speer 10mm 200gr Gold Dot Gel Test And Retraction

Published on August 13, 2018
Duration: 10:22

This video retracts previous velocity data for Speer 10mm 200gr Gold Dot ammunition due to an error by the presenter. New testing confirms velocities around 1000 feet per second, which is significantly higher than initially reported. The ammunition performed well in gel tests, meeting FBI recommendations, but showed inconsistent expansion in heavy clothing tests. The presenter speculates the lower velocity loading may be intended for subsonic use, potentially with longer barrels or suppressed shooting.

Quick Summary

The corrected average velocity for Speer 10mm 200gr Gold Dot ammunition, fired from a 4.5-inch barrel, is approximately 1000 feet per second. This ammunition performed well in bare gel tests, meeting FBI penetration recommendations, but showed inconsistent expansion in heavy clothing tests.

Frequently Asked Questions

What were the corrected velocities for Speer 10mm 200gr Gold Dot ammunition?

After retracting initial erroneous data, the corrected average velocity for Speer 10mm 200gr Gold Dot ammunition, fired from a 4.5-inch barrel, was approximately 1000 feet per second. This is about 170 fps faster than previously reported.

How did Speer 10mm 200gr Gold Dot perform in ballistic gel tests?

In bare ballistic gel tests, the Speer 10mm 200gr Gold Dot performed well, meeting FBI recommendations for penetration. Measured depths ranged from 12.9 to 15.5 inches, indicating effective performance.

What were the results of the heavy clothing test for Speer 10mm 200gr Gold Dot?

The heavy clothing test showed inconsistent expansion for the Speer 10mm 200gr Gold Dot. While some rounds expanded moderately, one round failed to expand at all, becoming clogged with denim and exiting the side of the gel block.

Why might Speer load 10mm ammunition at approximately 1000 fps?

The presenter suggests that loading Speer 10mm 200gr Gold Dot to around 1000 fps might be intentional for subsonic performance. This velocity is below the speed of sound and could be beneficial for suppressed shooting or use in firearms with longer barrels.
