Ballistics Test Summary

After firing five rounds of Federal 99 gr HST from a Glock 42 into synthetic ballistic gelatin from 10 feet away through four layers of fabric to simulate clothing, we then measured the expansion and penetration of the bullets for this .380 Auto (ACP) load, which you can see in the chart below.

The photos below provide a detailed view of the the expanded bullets that were recovered from the gelatin. The high-speed video shows the first of our five shots as it entered the gel.

Q: Wow, so it looks like this suffers from the same problem that the Hydra-shok does—no expansion. I've seen other tests where it does expand beautifully, but I think those were just into bare gel (not through denim). Do think the Tactical version of this would be any better, or not really?

Posted On: 1/26/2022 By: Eric

A: Thanks for reaching out Eric! I expect the law enforcement label version of Federal's HST ammo would perform identically to the Personal Defense load. They're identical, really, outside of their packaging. The HST is definitely a higher-quality JHP than the Hydra-Shok, but at the end of the day it's hard to get wide, consistent terminal expansion when you're working with the 380's limited power!

Q: Thanks so much for all of your work in this testing. I am wondering if the .380 Federal HST that you tested was the "micro" variant. Thanks!

Posted On: 1/22/2017 By: Josh

A: Hello Josh, The Federal HST .380 that was tested is the 99 grain "micro" product offering from Federal.
