Frequently Asked Questions

What ammunition was tested in the second part of the 9mm vs 40 S&W comparison?

In the second part of the comparison, the video tested 9mm Luger 124-grain +P Federal HST ammunition against 40 S&W 165-grain Speer Gold Dot ammunition. This setup aimed to address concerns about bullet types used in the previous test.

How did the 9mm HST perform compared to the 40 S&W Gold Dot in terms of expansion?

The 9mm 124gr +P HST ammunition demonstrated significantly better expansion in the ballistic gel test compared to the 40 S&W 165gr Speer Gold Dot. The HST bullets showed a 'wicked looking expansion,' while the Gold Dot had less noticeable expansion.

What were the penetration depths for the tested ammunition?

The 9mm HST achieved a maximum penetration of 16 inches into the ballistic gel. The 40 S&W Gold Dot reached approximately 18 inches, with the deepest penetrating round flirting with that mark. The instructor noted the 9mm HST achieved excellent penetration despite its expansion.

Which ammunition did the instructor believe performed better overall?

Based on the observed expansion and penetration in this test, the instructor expressed the opinion that the Federal HST ammunition, both in 9mm and the previously tested 40 S&W 180gr, outperformed the Speer Gold Dot ammunition.
