Federal Syntech Defense .40 S&W 175-grain Segmented Jacketed Hollow Point ammunition (part no. S40SJT1) delivers dynamic terminal performance from Federal, packaged here in a 20-round box for shooters who want to try the load before committing to a bulk case. On impact, the hollow-point bullet separates into three segments plus a deep-penetrating core, with that core reaching 12 to 18 inches through bare ballistic gel and heavy clothing, a critical benchmark for genuine self-defense performance. The three petals create secondary wound channels of their own, each more than 6 inches deep, adding to the round’s overall terminal effect. Like every Syntech load, an advanced polymer jacket eliminates lead and copper fouling while reducing barrel heat and friction, and Federal’s exclusive Catalyst primer delivers hot, reliable ignition without lead.
