Semi-Jacketed Soft Point Ammo: SJSP Bullets Explained
The semi-jacketed soft point (SJSP) is another hollow point alternative bullet – with an exposed lead soft point that gives very reliable expansion on impact, along with deeper penetration than your average hollow point.
You can usually find the semi-jacketed soft point with a copper jacket of various lengths and thickness to go with a lead core. Some manufacturers have this bullet in use with different materials, with a “lead-like” tip or other specialized components, so they can be used in regions where lead is banned. This particular bullet can be used for home defense, but you can also find them in rifle calibers for hunting.
Semi-Jacketed Soft Point Features
- Variety: This bullet can be found on tons of different ammo types, but is most commonly found in handgun calibers with a few manufacturers making them in rifle calibers. They are extremely versatile, and can be designated as target shooting, hunting, home defense, varmint control and more.
- Penetration: When hunting or protecting yourself and your family, a shallow shot can cause some major problems. The SJSP goes a bit deeper than a hollow point before the expansion initiates.
- Expansion: As mentioned above, the soft tip allows this bullet to expand once it hits the right depth in a target. In addition to expansion, many SJSP bullets deform and tumble as well. This can lead to a lot of internal damage, even with a badly placed shot. It takes some trial and error to see how certain brands of SJSP will perform.
Semi-Jacketed Soft Point Uses
This bullet can be used in most any application – home defense, big game hunting, target shooting, varmint control and more. Where an FMJ bullet is designed to retain its shape, this one is designed to deform and provide greater energy transference. That soft point can be in many different shapes, but the end result will always be the same – to flatten, tumble and cause a massive wound often twice as round as the bullet itself. It’s common for an SJSP bullet to bounce around inside a ribcage, guaranteeing even the most thick-skinned creature goes down fast.
SJSP is a great choice, because it can perform well in almost any situation. Although it does not stand out in any one particular area, it does well in virtually all of them. The only real downside is that there is usually lead used in this bullet, but some alternatives are available that swap lead for a non-toxic material. If you have a cache of ammo, you’re going to want quite a few boxes of SJSP in there to round things out and give you a great, all-in-one shot.
