Federal 9mm Luger (+P) 124 grain HST Attached File Federal’s Premium Law Enforcement Ammunition line-up currently includes four different 9mm Luger loads that utilize 0.355” versions of their hollow-point HST bullet. As the title states, the plus-P, 124 grain load (P9HST3) will be the focus of this article. All versions of the 9mm Luger HST ammunition are loaded in nickel-plated, brass cases. The case-head for the P9HST3 is stamped “F C 9MM + P”. This version is loaded to a cartridge nominal OAL of 1.100”. The primers are sealed, but are not crimped in place. The case mouths are also sealed. Attached File Attached File The 124 grain HST projectile has a nominal length of 0.595”. The bullet has a deep cannelure and six skives in the copper jakcet. The skives on the 9mm HST projectiles are the longest of any of the 9mm Luger law enforcement loads that I’ve evaluated to date. Attached File The 9mm HST projectiles have a very unique construction, in that the lead-core directly beneath the skives has a crown-shaped cut-out. Attached File Federal’s literature claims that the 9mm Luger (+P) 124 grain HST load has a muzzle velocity of 1200 FPS. When chronographed from my Gen 2 Glock 19 (with the factory original barrel) over an Oehler 35P chronograph, the P9HST3 load had a muzzle velocity of 1215 FPS with a standard deviation of 11 FPS! Dr. GK Roberts has stated that the 9mm (+P) 124 grain HST rounds “are among the finest 9 mm duty loads currently available.” Terminal ballistic testing in 10% ordnance gelatin conducted by the good doctor produced the following results . . . Attached File Attached File I evaluated the accuracy of the P9HST3 load from a distance of 25 yards using two different platforms; my Gen 2 Glock 19 and a Colt 6450 with a free-floated Noveske barrel. Attached File When using hand-loads topped with the Hornady 125 grain HAP bullet, my Noveske barreled Colt 6450 has turned in 10-shot groups at 25 yards that have extreme spreads of less than a half-inch. Attached File A 10-shot group of the P9HST3 ammunition fired from the Noveske barreled 6450 at 25 yards had an extreme spread of 0.98”. Attached File Firing from the bench at a distance of 25 yards, my Gen 2 Glock 19 (with the factory original barrel) produced a 10-shot group with an extreme spread of 2.29”. Attached File ….. |

Isn't the SB 124+p GD designed to operate at a lower velocity though? So even though it loses almost 6% from what it was through a Glock, shouldn't it's ideal window be what it comes out of the MK9 at? |

I sure hope so, since it has a lower muzzle velocity out of short barrels than the standard 124 grain +P load and it still looses a higher percentage of its velocity than the standard 147 grain load from the short barrel. ... |

I know it's not really your thing to do gel, but I'd dearly love to see a comparison in gel of the above rounds/guns |

The advertised muzzle velocity of the +P variant is 1050 FPS. I chronographed three different lots of the +P variant from the Glock 19. The average muzzle velocity was 1029 FPS. ... |

I have heard that about 8-10 years ago Federal lowered the velocity of their HST 9mm loadings. I believe this was documented by several youtube testers. The velocity drop was only 20-30FPS, basically the +P went down to the non +P velocity. HST in 9mm was very honest with the velocity they stated back then. If the box said 1050fps, you'd probably get 1060 out of a G17. The non +P is listed at 1000FPS and it was not unusual to get over that by a little. This is in contrast to other manufacturers that had measured velocity always a good 50 FPS LOWER than what was on the box. Molon, have you had the chance to compare new lots of HST to the stuff you tested back in 2016 and prior? |

Good confirmation of a good bullet from a trusted source. Thanks Molon. |
