Winchester
Winchester 9mm .355 124 gr Full Metal Jacket (FMJ) bullets are engineered component rounds built for handloaders who demand consistency and reliability. Whether you're assembling match-grade practice loads, building duty-carry ammunition, or developing a load for your preferred 9mm platform, these FMJ projectiles deliver the precision and uniformity that separates thoughtful reloading from assembly-line guesswork. A 500-round box gives you the volume to work through ladder tests, load development, and sustained practice without constantly resupplying.
Full metal jacket construction makes these bullets ideal for indoor range work and high-volume practice, where lead exposure and cleanup are concerns. The 124-grain weight is one of the most popular choices for 9mm—it strikes a practical balance between velocity, recoil, and barrel wear across the full spectrum of firearms that chamber the cartridge, from compact carry guns to competition setups. Winchester's manufacturing standards ensure neck-to-neck consistency from bullet to bullet, which translates to tighter groupings and more predictable ballistics once you dial in your load.
If you're new to handgun reloading, these bullets pair well with standard 9mm dies, small pistol primers, and common powders; if you're already established, you know Winchester component bullets earn their place in serious reloaders' benches. The 500-count packaging also makes it easy to track usage and inventory across multiple load development sessions.
| Caliber | 9mm |
| Bullet Diameter | .355" |
| Weight | 124 grains |
| Bullet Type | Full Metal Jacket (FMJ) |
| Quantity Per Box | 500 |
| Brand | Winchester |
These bullets are sized for standard 9mm/.355 inch diameter cartridges and will work in any firearm that chambers 9mm, including pistols, carbines, and submachine guns. Always verify that your specific firearm's chamber and bore specifications are compatible with .355 inch projectiles and that your reloading dies are properly set for 9mm.
Full metal jacket bullets are primarily designed for target practice, training, and high-volume shooting. For defensive loads, consider hollow-point or other purpose-designed defensive bullet types. Always follow local laws regarding ammunition types and use cases.
A 500-count box gives you 500 individual bullets, so you can assemble 500 complete 9mm cartridges (assuming you have adequate primers, powder, and cartridge cases). This is a practical volume for load development, testing, and sustained practice.
Winchester component bullets are designed to work with standard 9mm reloading components. Consult published reloading manuals for your specific powder and small pistol primer choices, as load data varies by powder type and primer brand. Always follow established load data and reloading safety practices.
