Winchester WB9FB115D 9mm 115gr FMJ Flat Base Bullets - 500ct

The Winchester WB9FB115D delivers consistent performance for serious reloaders working with 9mm ammunition. These 115-grain full metal jacket flat base bullets provide the reliability and accuracy needed for high-volume loading operations. Built to Winchester's exacting standards, these components maintain tight tolerances shot after shot.

What Makes This Different

Winchester's flat base design optimizes bullet seating consistency compared to boat tail alternatives in pistol cartridges. The full metal jacket construction ensures reliable feeding through semi-automatic actions while maintaining structural integrity during loading operations. Each bullet undergoes quality control testing to verify weight consistency within +/- 0.5 grains, delivering the uniformity competitive shooters and training facilities demand.

Key Features

• 115-grain weight optimized for standard 9mm velocities and reliable cycling
• Full metal jacket construction prevents lead fouling in barrel and chamber
• Flat base profile ensures consistent seating depth and powder compression
• Copper-plated jacket reduces barrel wear during high-volume shooting
• Bulk packaging of 500 bullets reduces per-round cost for volume reloaders
• Diameter held to .355" +/- .001" for consistent chamber fit
• Compatible with standard 9mm reloading dies and equipment

These bullets perform consistently across competition, training, and recreational shooting applications. The 115-grain weight cycles reliably in compact and full-size pistols while generating manageable recoil for rapid follow-up shots. Range testing shows consistent accuracy potential when loaded with appropriate powder charges and proper seating depth. The copper jacket maintains integrity through feeding cycles in high-capacity magazines.
