Winchester SUP400 Super Suppressed 400 Legend 300gr Open Tip 20rd

The Winchester SUP400 Super Suppressed ammunition delivers optimized subsonic performance for 400 Legend firearms equipped with suppressors. This specialized load reduces noise signature while maintaining terminal effectiveness through its heavy 300-grain open tip projectile design.

What Makes This Different

Engineered specifically for suppressed firearms, this ammunition operates below the sound barrier to maximize suppressor effectiveness. The 300-grain open tip bullet provides controlled expansion and deep penetration compared to standard supersonic loads. Subsonic velocity eliminates the sonic crack that standard ammunition produces, creating a significantly quieter shooting experience.

Key Features

• 300-grain open tip projectile for controlled expansion and penetration
• Subsonic velocity optimized for suppressor use
• Consistent powder charge for reliable cycling in semi-automatic actions
• Nickel-plated brass cases resist corrosion and enhance extraction
• Boxer-primed cases suitable for reloading
• 20 rounds per box, 10 boxes per case (200 total rounds)
• Compatible with all 400 Legend chamber specifications

This ammunition performs reliably in both bolt-action and semi-automatic 400 Legend platforms. The heavy bullet weight maintains energy downrange while the subsonic velocity prevents accuracy-disrupting turbulence. Hunters appreciate the reduced noise signature for follow-up shots, while recreational shooters benefit from decreased hearing protection requirements. The open tip design ensures consistent expansion in hunting applications while maintaining accuracy for precision shooting.
