10mm Federal Premuim HST (200GR) is my go to defensive round. It's fast, dumps a lot of energy and if ballistic gel is telling, expands cleanly and uniformly. This great ammo is made even better with Velocity's bulk deal pricing, which in turn provides me the opportunity to truly "train how I fight" with the ammo that I carry.
My only gripe is that Federal markets this as "full power" 10mm. My chrono was reading roughly ~1120 to 1130 FPS velocity out of my Smith & Wesson 10mm M&P 2.0 (4.6") and Glock 20SF Gen 3. While I do not consider myself a 10mm purist by any stretch of the imagination, when I hear or read 10mm full power, I'm expecting 200GR moving at the very least at 1200 FPS. Whatever the case may be, this ammo has yet to fail me and I'll definitely be back for more, kudos to the fine folks of Velocity Ammo who've made shooting affordable again!
