Jacketed Hollow Point (JHP) Bullets Explained
The jacketed hollow point (JHP) is designed to expand rapidly when hitting its target which increases the effectiveness of the bullet and decreases the chances of over penetration. Jacketed hollow points come in a massive variety, separated by shape, design or simply the company that manufactures them. Some will look just like traditional hollow points but be obviously coated while others will have a more advanced and high tech appearance. The nose is coated in a harder metal, helping prevent lead issues in your gun as well as the air and ground and the coating also helps this type of ammunition function better in automatic feeding pistols and rifles.
Jacketed Hollow Point Features
Jacket – This is going to be the number one reason this type of bullet is chosen over traditional hollow points. The main advantage of a jacketed bullet is easier feeding in semi auto pistols. Another advantage is less lead fouling in your barrel. If you shoot a lot of ammo through any weapon this can lead to performance issues and wear and tear.
Expansion – Hollow points are designed to expand when they strike a target to cause extra damage and also prevent over-penetration issues. This is perfect for home defense and concealed carry, as well as hunting and makes a fun choice for shooting melons and water jugs.
Variety – You can buy this type of bullet in a huge variety of shapes and styles. Each manufacturer will have special lines for hunting, long range shooting, target practice or defense. You can usually find pistol and rifle varieties making this and other hollow points very versatile. Some of the most popular calibers for the JHP cartridge are: .38 Special, .45 ACP and 9mm
Jacketed Hollow Point Advantages
The most noticeable advantage any hollow point has over a normal bullet is its stopping power. When you hit a living target like a deer with a HP bullet, it’s going to cause significant damage unless it grazes it. This usually guarantees the animal is going to drop immediately or not get very far. Hollow points are considered a more “humane” ammo type for hunters. These same properties carry over for home defense use.
The jacketed hollow point will feed better than lead nosed hollow points in most weapons that use a magazine be it a pistol or rifle. The jacket has a much smoother surface with less variation from bullet to bullet than traditional lead.
Jacketed Hollow Point Disadvantages
The only real disadvantage a JHP bullet may have is expansion issues with thick clothing. This isn’t experienced much and for typical home defense ammunition the odds of this being an issue is extremely slim. Some reloaders have experienced this by not loading the round properly or when using experimental mixtures. For factory ammo, specific use ammo lines or properly reloaded ammo you shouldn’t have any problems at all.
Jacketed hollow points are very popular because they tend to get the job done and perform very well in most capacities where a hollow point is desired but the lead nose is not.
