<\/p>\nThe jacketed hollow point (JHP) is one of the most common types of bullets available on the market. Designed for expansion at the target, these rounds are intended to stop threats and drop game animals effectively.<\/p>\n
Whether you are an experienced hunter, a concealed-carry permit holder, or a target-shooting enthusiast, you need to understand the benefits and drawbacks of these common bullets.<\/p>\n
<\/p>\n
A hollow point (including jacketed and unjacketed) is essentially a bullet that has a pit or bowl in the nose. This pit is intended to cause expansion when the bullet strikes a target. Hollow point bullets come in a large variety of sizes, cartridges, and shapes, but the overall feature is this pit at the nose.<\/p>\n
However, jacketed hollow points have another defining feature: the jacket, which is a hard copper exterior casing that covers the soft interior lead core of the bullet. The jacket brings two distinct advantages over unjacketed cartridges.<\/p>\n
First, is cycling. In a semi-automatic firearm, lead bullets sometimes create feeding issues and jams when the cartridge is cycled from the magazine to the chamber. However, with a jacket, the feeding process is smoother and more consistent. Jacketed hollow points do not eliminate jams, but they do reduce them.<\/p>\n
The other advantage of the jacket is less fouling. Fouling is a residue left in the barrel when the bullet is ejected. Lead is much softer than copper and leaves more fouling. So, having a copper jacket will delivers better accuracy and performance over multiple shots while maintaining the quality of a barrel.<\/p>\n

Firing a projectile that expands at the target had been experimented with for years, but it wasn\u2019t until roughly the late 19th century that manufacturers marketed hollow points to the general public. It\u2019s believed that the initial goal of the hollow point design was actually to increase speed.<\/p>\n
To reduce weight, manufacturers took out some of the bullet\u2019s mass at the center of the nose. During testing, they discovered that speed gain was minimal at best. They also noticed the bullets provided greater expansion and a new purpose for the design was born.<\/p>\n
Up to this point in history, we\u2019re talking about the basic hollow point, without the addition of jacketing. It\u2019s believed that the jacketed hollow point was invented in India during the late 19th century. At the Dum Dum Arsenal<\/a>, a British captain developed a mull-metal jacket round with the jacket cut away at the nose. This exposed the lead core. The bullet became known as the \u201cdum-dum,\u201d an early precursor to the jacketed hollow point that we know today.<\/p>\n You have to know how these perform both internally and externally to decide whether their use is right for your purposes.<\/p>\n If you are concerned with bullet speed, jacketed hollow points will make little difference. Overall velocity, both from the muzzle and down range, appears to be unchanged. There also appears to be no difference in the amount of power that is delivered when a bullet lands at target. However, there is a change in how the power is used. (See Terminal Performance <\/em>below.)<\/p>\n As an example, 115-grain 9mm Luger rounds from Federal Ammunition in jacketed hollow points and full metal jacket (American Eagle<\/a>) have the exact same ratings for velocity and energy from start to finish.<\/p>\n The accuracy of a jacketed hollow point verse a full metal jacket round is a complex debate with no clear answer.\u00a0It depends on so many factors, such as the cartridge, the firearm, bullet weight, and wind direction.<\/p>\n It\u2019s a reasonable assumption that full metal jacket and soft point rounds would be more accurate, as the bullet is more streamlined; however, some believe that JHP rounds are more accurate because the bullets have better balance. Like most aspects of firearms, you need to try multiple options to see which is right for you.<\/p>\n Terminal performance is where jacketed hollow points have a distinct, undoubted advantage.<\/p>\n The expanding nature of the bullet creates more lethal and effective wounds. This allows users to stop threats or drop game with greater effectiveness. As the bullet expands, it also slows and stops in the target, which makes it less dangerous for others. With full metal jacket rounds, there is a chance that the bullet could travel through the target (or a barrier such as drywall) and harm another person.<\/p>\nPerformance of Jacketed Hollow Point Ammunition<\/h2>\n
