Winchester AmmoCenterfire Handgun Reloading 9mm .355 115 gr Full Metal Jacket Flat Base (FMJFB) 500 Per Box

Winchester 9mm reloading bullets are a straightforward, reliable choice for handloaders working up ammunition for 9mm Luger (9x19) firearms. These 115-grain full metal jacket flat base bullets deliver consistent performance across a wide range of handgun platforms—from duty and competition pistols to casual range guns. Whether you're building practice ammo, match rounds, or working through load development, Winchester's proven cup-and-core construction and quality control make them a solid foundation for repeatable, accurate loads.

The flat base design simplifies seating in most standard reloading dies and helps maintain bullet stability through the chamber. At 115 grains, this weight is a common choice for 9mm—it balances velocity, recoil, and reliable function across modern semi-automatic pistols. Full metal jacket construction means these bullets are suitable for indoor and outdoor range use, and they're designed to handle the pressures and velocities typical of common 9mm loads.

Each box contains 500 bullets, giving you enough for a serious reloading session or to stock up for ongoing practice and match prep. Winchester backs these components with the reputation they've built over more than a century in ammunition manufacturing. If you reload for 9mm regularly, bulk quantities like this make economical sense, and the consistency you expect from Winchester helps you build loads you can depend on.

Frequently Asked Questions

What firearms are these 9mm bullets compatible with?

Winchester .355 diameter 9mm bullets are designed for 9mm Luger (9x19) handguns. They'll work with any standard semi-automatic pistol or revolver chambered in 9mm, including modern service pistols, competition guns, and casual range firearms.

Are these bullets suitable for both indoor and outdoor range use?

Yes. The full metal jacket design makes them appropriate for both indoor and outdoor shooting. FMJ bullets are commonly used for range practice, training, and competition where lead-free or lead-contained impact is preferred or required.

How many rounds can I load with one box?

Each box contains 500 bullets. The total number of finished rounds depends on your powder, primer, and cartridge case choices, but one box of bullets will load 500 rounds (one bullet per round).

What does "flat base" mean, and why does it matter?

A flat base means the bottom of the bullet is flat rather than concave (hollow) or shaped. Flat base bullets are straightforward to seat in standard reloading dies and provide consistent baseline performance. They're a conventional, proven design for 9mm handgun reloading.
