Enclosing the core is a rigorously engineered copper jacket. This jacket performs a crucial function in a number of areas: sustaining structural integrity throughout affect and enabling dependable enlargement; and likewise offering the rifling of the barrel with an interface.
The Core
The core itself is usually fabricated from lead alloy, optimized for managed enlargement and penetration. The core’s properties are rigorously matched with the jacket to make sure dependable efficiency at a spread of velocities. The design helps the bullet mushroom predictably, rising its diameter and transferring extra power to the goal.
Ballistic Coefficients and Sectional Density: Understanding the Numbers
Ballistic Coefficient (BC) is a numerical worth that signifies how nicely a bullet resists air resistance. A better BC means the bullet will retain its velocity and power over longer distances. Sectional Density (SD) is a measure of a bullet’s capability to penetrate. It’s calculated by dividing the bullet’s weight by its diameter squared. A better SD typically means the bullet will penetrate deeper. The 158-grain XTP affords a superb stability of each. Whereas not a long-range projectile, its BC permits for a comparatively flat trajectory, and its SD contributes to its capability to penetrate successfully.
Efficiency on the Vary and within the Discipline

Enlargement
The enlargement traits of the XTP are well-known. Upon affect, the hole level expands, rising the bullet’s diameter and the scale of the wound channel. Enlargement diameter sometimes ranges from round .50 inches to .75 inches, relying on the affect velocity and the goal.
Penetration
The 158-grain weight offers good penetration, making it appropriate for each self-defense and searching. The XTP design is engineered to keep up its structural integrity throughout affect, making certain ample penetration to achieve very important organs. Penetration depth will range relying on the goal medium, however anticipate vital penetration in tender tissue and potential for deep penetration in varied searching situations.
Stopping Energy
The mixture of enlargement and penetration contributes to the general stopping energy of the Hornady 158 Gr XTP 357. The expanded bullet delivers vital power switch to the goal, incapacitating it rapidly and effectively.
Functions and Makes use of: The place the XTP Shines
The Hornady 158 Gr XTP 357 has earned a status for its effectiveness in varied functions.
Self-Protection
The .357 Magnum, loaded with the 158 gr XTP, is a extremely efficient possibility for private safety. The mixture of manageable recoil, good penetration, and dependable enlargement makes it a robust selection for hid carry and residential protection. It offers a stage of energy that may cease a risk rapidly, and the XTP’s design minimizes the chance of over-penetration.
Searching
The .357 Magnum, using this explicit Hornady XTP loading, is well-suited for searching small to medium-sized sport, reminiscent of deer, coyotes, and wild hogs. The managed enlargement and deep penetration of the XTP guarantee moral kills. The cartridge’s efficient vary in a searching software requires cautious consideration, with pictures sometimes saved inside 100 yards.
Goal Taking pictures and Plinking
