Optimized for Suppressed Shooting
The Winchester Super Suppressed 22LR is specially engineered to perform flawlessly with suppressors. Each round is loaded to subsonic velocities, eliminating the sharp “crack” associated with supersonic rounds breaking the sound barrier. This results in significantly quieter shots, ideal for backyard target practice or hunting in noise-sensitive areas.
Subsonic Velocity: Delivers a consistent, low-noise signature that enhances suppressor performance.
Reduced Gas Blowback: Cleaner powder burns minimize residue and suppressor fouling.
Dependable Cycling: Designed for reliable feeding and function in semi-automatic firearms.
Even without a suppressor, these rounds produce smoother recoil and less muzzle blast, making them enjoyable for shooters of all ages and experience levels.
45-Grain Black Copper Plated Round Nose (BPRN)
Each cartridge features a 45-grain black copper plated round nose bullet, carefully designed for balance, accuracy, and reduced fouling. The copper plating prevents excessive barrel lead buildup, extending cleaning intervals and preserving your firearm’s accuracy over extended shooting sessions.
Heavy 45gr Bullet: Offers superior momentum for reliable cycling and consistent point of impact.
Copper Plating: Reduces barrel wear and residue buildup compared to traditional lead bullets.
Round Nose Design: Ensures smooth feeding in semi-automatic actions and precision alignment in bolt guns.
This bullet design is ideal for target accuracy and small-game hunting, producing tight groups and consistent terminal performance.
Ultra-Clean Powder and Primer Technology
Winchester’s Super Suppressed line features proprietary powders and primers formulated for clean combustion and reduced carbon buildup — essential for maintaining suppressor efficiency and firearm longevity.
Cleaner Burn: Less carbon and unburned powder reduce maintenance requirements.
Consistent Velocity: Precision powder charges ensure uniform speed and accuracy.
Reliable Ignition: Winchester’s time-tested primer technology guarantees dependable ignition, even under varied conditions.
