Ok, it's painful for me to admit this, but I am not familiar with JSP rounds. Though the BAR rocks. Of course I never had to hump one in country.
Jacketed Soft Point. Available in both
Rifle and
Handgun cartridges.
Basically hunting rounds, with a small bit of exposed lead at the tip. They're designed for controlled expansion, to allow greater penetration before mushrooming.
Much better than hollow points for thick skinned animals, as the hollow points usually expand too fast and don't provide enough penetration. Better than full metal jackets for most hunting, as full metal jackets generally don't expand. There are times you will want a solid core bullet for maximum penetration, but that's generally only when hunting large African game.
It's pretty much the jack-of-all-trades when it comes to projectiles. In my opinion, it's one of the most versatile loads available.
If you want even better performance, there are even improved versions of the jacketed soft point such as the
Nosler Partition...
Hope this helps!
