Winchester SUP350 Super Suppressed 350 Legend 255gr OTR Ammo

The Winchester SUP350 Super Suppressed ammunition delivers optimized performance for suppressed 350 Legend firearms with reduced noise signature and consistent accuracy. This specialized load features a 255-grain Open Tip Range bullet engineered to maximize subsonic velocity while maintaining reliable cycling in semi-automatic platforms.

What Makes This Different

Unlike standard 350 Legend ammunition, the SUP350 operates at subsonic velocities specifically engineered for suppressed shooting. The heavy 255-grain bullet weight ensures consistent subsonic performance across various barrel lengths while the Open Tip Range design provides enhanced accuracy compared to traditional FMJ loads. This ammunition eliminates the sonic crack associated with supersonic rounds, maximizing the effectiveness of sound suppression equipment.

Key Features

• 255-grain Open Tip Range bullet optimized for subsonic velocity
• Engineered specifically for suppressed 350 Legend firearms
• Consistent powder charge ensures reliable semi-automatic cycling
• Boxer-primed brass cases suitable for reloading
• Velocity approximately 1,060 fps from 16-inch barrel
• 20 rounds per box, 10 boxes per case (200 total rounds)
• Compatible with all 350 Legend chambered rifles and pistols

This ammunition excels in hunting applications where noise reduction is critical, particularly in suburban areas or properties with noise restrictions. The subsonic velocity maintains effective terminal performance on medium game within appropriate ranges while significantly reducing report when used with quality suppressors. Range training becomes more comfortable for both shooter and nearby personnel, making extended practice sessions more practical.
