Underwood Ammunition 357 Sig 147 Grain Hornady XTP Jacketed Hollow Point Box of 20

Underwood Ammunition 357 Sig 147 Grain Hornady XTP Jacketed Hollow Point Box of 20 pairs Underwood’s high-pressure loading with the proven Hornady XTP bullet at a heavy weight. Because the 147 grain XTP ranks among the heaviest options for this cartridge, it retains momentum well past typical defensive distances. The XTP’s serrated jacket and precisely cut cavity promote controlled, predictable expansion across a wide range of velocities.

Heavy-Bullet Terminal Ballistics

As a result, shooters who want deep penetration alongside dependable expansion often favor this load, particularly through automotive glass. Underwood hand-inspects each loaded cartridge, and the brass holds up well under the 357 Sig’s naturally high chamber pressure. Meanwhile, the bottlenecked case feeds with the same reliability that made this cartridge popular with federal agencies.

The heavier bullet weight also slightly tempers muzzle blast and flash compared to lighter offerings in the same case. For best results, pattern this load through your specific pistol first, since barrel length changes velocity meaningfully. Similarly, many hunters choose this weight for small to medium game, since it gives flat, controlled expansion.
