Winchester SUP22LR Super Suppressed 22LR 45gr BCPRN 100rd Box

The Winchester SUP22LR Super Suppressed ammunition delivers subsonic performance specifically engineered for suppressed firearms. This 22LR cartridge features a 45-grain black copper plated round nose bullet that maintains reliability while minimizing sound signature through suppressors.

What Makes This Different

Unlike standard velocity 22LR ammunition, the SUP22LR operates at subsonic velocities to eliminate the supersonic crack that defeats suppressor effectiveness. The black copper plating reduces barrel fouling compared to standard lead bullets while maintaining consistent feeding in semi-automatic firearms. Winchester's subsonic loading ensures the bullet remains below 1,080 fps, maximizing suppressor performance without sacrificing accuracy.

Key Features

• 45-grain black copper plated round nose bullet for reliable feeding
• Subsonic velocity eliminates supersonic crack through suppressors
• Reduced barrel fouling compared to standard lead bullets
• Consistent powder charge for repeatable accuracy
• 100 rounds per box, 20 boxes per case (2,000 total rounds)
• Compatible with all 22LR firearms and suppressors
• Brass cases suitable for reloading applications

The SUP22LR performs exceptionally in suppressed training scenarios, small game hunting, and precision shooting applications where noise reduction is critical. The subsonic velocity maintains sufficient energy for effective terminal performance on small game out to 50 yards while keeping noise levels to a minimum. The black copper plating extends barrel life during high-volume shooting sessions.
