Federal Premium Ammunition 357 Sig 125 Grain HST Jacketed Hollow Point Box of 20

Federal Premium Ammunition 357 Sig 125 Grain HST Jacketed Hollow Point Box of 20 loads the HST bullet, a design engineered to eliminate the weak points found in earlier hollow point profiles. The HST’s skived jacket and reinforced base resist petal breakage. It holds its expanded diameter and weight far more consistently than older designs. Federal built this bullet to expand reliably. It performs well even after it passes through heavy clothing, wallboard, or auto glass.

Engineered Petal Retention

As a result, HST has become a widely issued duty round among federal and local law enforcement agencies nationwide. The 125 grain weight matches the traditional benchmark for the 357 Sig, balancing expansion, penetration depth, and manageable recoil. In addition, Federal’s nickel-plated cases resist corrosion, which matters for a round that stays chambered in a carry pistol for long periods.

About This Federal Premium Ammunition 357 Sig 125 Grain HST Jacketed Hollow Point Box of 20 Load

Federal designed HST after it studied the specific failure modes that caused earlier hollow points to underperform in real shootings. Notably, independent testing consistently shows HST meeting FBI protocol penetration and expansion standards across nearly every tested barrier type. Consequently, many trainers and agencies treat this loading as a top-tier default choice for duty and concealed carry.
