Quick Look

Full Metal Jacket (FMJ) bullets were first developed in the late 19th century to improve feeding reliability and penetration in military firearms.

FAQs

Can I use Full Metal Jacket bullets for self-defense?

Yes, but FMJs lack expansion, reducing stopping power. Hollow points are generally preferred for defense.

What is the main advantage of Full Metal Jacket bullets?

How does a Full Metal Jacket bullet differ from a hollow point?

FMJs have a hard metal jacket encasing the core, while hollow points are designed to expand on impact for greater damage.
