Rated 5 out of 5 by from great ammo Great educational round. I've only had one hang up out of the 100s of boxes I've purchased in the last years. Roger LCPs and Smith and Wesson 380s. Its amazing what this round does to a body. We educate with body jello and for all our clients. They never leave disappointed with the knowledge and being able to see the damage. Great job on these rounds.

Rated 1 out of 5 by from Appears useless for me I can't even rack the slide on my LCP Custom without problems. The rounds hang up, stick before crossing the feed ramp, and sometimes even stovepipe (live rounds, I mean) while trying to eject after. I never had the chance to fire a round. Seems that's probably a good thing, all things considered.

Rated 5 out of 5 by from 380 auto Hydro Shok 99 grn. Bought a Ruger LCP II 380 and ran this ammo through it flawlessly. But alot of recoil from the tiny pistol! "GREAT RESULTS!"

Rated 1 out of 5 by from Don't use in Ruger LCP II ! Recently purchased a Ruger LCP II for a backup piece. Sighted Viridian laser and practiced with Winchester FMJ without problem. Fired Federal HST and gun kicked like I'd stuck a +P load in it. Then casing stuck in slider on ejection, crumpling casing. Tried two more shots and had same result. Stopped shooting them for fear of damaging pistol

Rated 5 out of 5 by from love it!!!!! I saw these while shopping for some ball ammo while at walmart. Took the chance and bought a box. I have been a huge fan of the hst for years. I went out to the range with four water jugs, one gallon each. Fired one round in to the water jugs, recovered that bullet in the third jug. dented the back wall of the third jug. The distance was at 15-20 yards or so. test gun is my bersa thunder 380. these are my carry rounds both in town and in the southern oregon woods.

Rated 4 out of 5 by from Non Scientific test Fired at 30 feet into four layer denim covering two Tide detergent bottles filled with water. Bullets transited both containers round hole in and out all four sides target without stopping. One bullet recovered was clogged with denim failed to expand. Fired into a five gallon bucket filled with water covered with four layers denim, penetrated the denim and one side of bucket bullet recovered hollow point filled with denim, no expansion. Penetration was good, the bullet strike was powerful. Operation in my Taurus TCP was flawless, recoil while sharp was manageable. Overall a good defensive round I'd say.

Rated 5 out of 5 by from Excellent Velocity and consistency I chronographed 5 of these at 11.5' from a 3.25" bbl Glock G42: 1023, 992, 984, 1007, 1018. Sample mean was 1005 fps, sample standard deviation 17 fps. 1009 fps corrected to muzzle. Impressive velocity and low standard deviation from a short barrel. Excellent job Federal.
