Understanding 9mm bullet types explained ensures your firearm functions reliably while delivering the right impact. At Bulk Ammo Supply, we provide the technical data you need to choose between high-volume training rounds and premium duty loads.
9mm Bullet Types Explained: FMJ vs. JHP
1. Full Metal Jacket (FMJ)
Commonly called “ball ammo,” the FMJ features a lead core covered in a hard copper shell.
- How it works: These rounds are designed to keep their shape upon impact.
- Best for: This is the best 9mm for range use, target practice, and tactical drills.
- Pros: Lower cost per round and extremely reliable feeding in semi-auto pistols.
- Cons: High risk of “over-penetration” (passing through targets), making it poor for home defense.
2. Jacketed Hollow Point (JHP)
Hollow points feature a recessed tip designed to expand or “mushroom” when they hit a target.
- How it works: The open tip uses fluid pressure to peel back the metal, doubling the bullet’s width.
- Best for: Self-defense, law enforcement, and home protection.
- Pros: Maximum stopping power and a reduced risk of hitting anything behind your target.
- Cons: Higher price point due to complex manufacturing.
