All three loads tested in this event offer acceptable terminal performance for LE duty use. The Federal HST, like the Winchester Ranger Talon and Speer Gold Dot, offers a bit more expansion and slightly less penetration, a possible advantage for municipal LE agencies patrolling urban or crowded suburban environments. Like Hornady Critical Duty, the Speer G2, and Winchester bonded loads penetrate a bit deeper, but have less expansion than HST and might offer an advantage for agencies with a significant number of engagements around vehicles or for rural agencies where larger animals are a potential threat.

It is strongly recommended that LE agencies approve at least two similar loads from different manufacturers, to help ensure a consistent supply of ammunition in times of scarcity. In other words, if an agency adopts HST, it would be prudent to also approve a load with similar terminal performance, like Ranger Talon or loads using Barnes Tac-XP projectiles; alternatively, if an agency adopted Speer G2, it would be smart to also authorize Hornady Critical Duty or Winchester bonded loads, as they will perform in like fashion.

Vyse Type 250 A ordnance gelatin was mixed into 8” x 12” x 20” blocks of 10% concentration and stored at 4 deg. All gel was validated with a standard .177 inch BB fired into the blocks with a velocity of 590 f/s +/- 15 f/s, with an ideal range of penetration defined as 8.5 cm +/- 1.0 cm of penetration (
although up to +/- 1.5 cm was considered acceptable). In this test, five rounds of each handgun ammunition type were fired into the blocks of validated ordnance gelatin from a range of ten feet. Shots were made into bare gelatin, gelatin covered with 4 layers of denim (IWBA protocol), and through laminated automobile windshield glass angled at 45 degrees, placed 18 inches in front of the gelatin block. All test shots were conducted using a 9 mm Glock 19 with OEM barrel.

Take care, keep safe, stay frosty, brother!

Doc, would you recommend the 147gr offerings listed above over their 124gr counterparts?

Thanks

Doc, in addition to what HE just posted above me, which I am very interesting in hearing the answer since I actually carry a G19.  Also, have you had a chance to do any testing with the above ammo in  either/both 124 and 147 out of a Glock 43?  I have heard, but have no personal knowledge of, that 147 HP varieties do not expand well out of the pocket type small frame guns ie: the glock 43.

Don't look at me in that tone of voice

 

Thanks Doc... Excellent information.  I'm glad to hear your recommendation for two loads as our agency just switched to HST but I argued (successfully) to keep the Ranger-T as an authorized load.  I carry the HST but still have a bunch of Ranger-T in various spare mags and such. 

Regarding TROPLEO's post, and hopefully not to step on Doc's toes, but when my agency tested the HST and Ranger-T in a S&W Shield, the HST showed very consistent expansion and markedly better performance in that area than the Ranger-T.  I don't have the results with me (they are at work) so I can't speak to penetration but I would say our results echoed Doc's post that the HST penetrates a bit less but seems to display more consistent expansion, especially in short barreled autos.   I still wouldn't feel bad with Ranger-T in my Shield, but I feel better with HST.

This is good info.  (Has anyone ever seen any video with that uber slow-motion of a round like this going through the glass, before it goes into the  ballistic gel?  I would be curious to see a close up video  using that million frames a second photography to see the round go through the glass and then into the gel.)
