Federal HST- Impressive performance!

[Buckeye]

Is this an LE only round?

I would guess that 'H' stands for 'Hi-' or 'Hydro-' or 'Hydra-'...
I would guess that 'S' stands for 'Shok' or 'Shock'...
And... I would guess that 'T' stands for 'Technology'...

When it was developed, the design engineer told me, "Hi-Shok Two".

'Hi-Shok Two' it is, then...

Just one person's experience with one ATK wound ballistics workshop in Fort Worth , but the first gelatin block was calibrated initially at the beginning but the other blocks sat outside until they were shot and were not calibrated or the temp checked prior to use. I'm fairly certain that they were warmer than they should have been and without calibration the data was suspect, at best.

The HST is a solid bullet design but the ATK workshop data should not be considered sacrosanct.

Gomez,

You are correct, the data from the warmer blocks would make the bullets seem to penetrate further.

The entire procedure should actually be suspect...

Can't talk about it yet but the 147gr HST seems to penetrate just fine in my observation.

I've been having a discussion with a guy over on Arfcom who has shown problems with 147gr HSTs when shooting them into water. Here is the pic he posted:



He also fired 115gr DPX and 124gr +P HST and 124gr GDHPs which all expanded perfectly. The gun used is a 3.5" M&P supcompact.

This is kind of unsettling. Would there be any reason to expect the 147gr HSTs to have lost enough velocity out of a 3.5" barrel to not expand properly?

I would not expect there to be a good reason for lack of expansion from a 3.5 inch barrel... the velocity shouldn't be that much lower than say from a Glock 17...
