Semi-Jacketed Hollow Point (SJHP) Bullets Explained
The semi-jacketed hollow point is a bullet designed to give you all the stopping power and expansion of a normal hollow point but with a bit more penetration.The partial jacket acts as a platform for creating a predictable and uniform mushrooming effect upon impact with a target.
This particular bullet type saw a lot of action in the 1970’s and 1980’s with Remington’s “scalloped” line being one of the most popular among law enforcement personnel who favored revolvers. Some still use them today if they carry a service revolver and this bullet type is allowed in their region.
This isn’t being produced by popular manufacturers as much anymore so it’s become one of those types of ammo that people find somewhere and buy all they can if it’s a favorite. Besides Remington, Fiocchi, and Magtech are the most easily found brands that still make SJHP ammo .
Semi-Jacketed Hollow Point Features
Semi-Jacketed – Naturally, this is what you’re going to be looking for specifically when checking out ammunition featuring this type of bullet. You have a great balance here between the penetration of an FMJ and the expansion of a soft nose or non-jacketed bullet. Different brands will perform very differently so you’ll need to head out to the range to get a good feel for the penetration of any SJHP ammo.
Hollow Point – The hollow point of the SJHP bullet can be produced with various levels of depth and diameter and this will influence how well it expands upon impact with a target. Each brand will have a different hollow point in any bullet type including semi-jacketed. It can really pay off to experiment if you plan to use these for home defense and you’re concerned about over-penetration.
Semi-Jacketed Hollow Point Uses
This bullet was designed for pretty much one use and that is self-defense. You get more stopping power than a standard bullet due to the hollow point and a nice amount of penetration to make sure the bullet isn’t going to simply lose velocity too fast once it hits a target. As with any hollow point, when a target is hit, the nose mushrooms outward from the center creating a much larger than average wound cavity. This is to make sure when you need to stop someone, they go down with one shot as long as it’s in a vital area.
Overall this is a popular bullet type for use in home defense ammunition. It’s lost some of its standing in the market over the past couple of decades as new technology has created nice alternatives that fill this particular niche. Some people like the semi-jacketed hollow point for backyard shooting and pistol target shooting because it creates a very satisfying hole in whatever you’re shooting at. Today it is most commonly found in revolver calibers such as .38 Special, .357 Magnum and .44 Magnum.
