Winchester Double X 12GA 00 Buck 2.75" High Velocity - 5 Rounds

The Winchester Double X SB1200 delivers maximum stopping power with 9 pellets of 00 buckshot in a high-velocity 2.75-inch shell. This premium defensive load combines Winchester's proven powder technology with precision-formed lead pellets for devastating terminal performance when it matters most.

What Makes This Different

Double X ammunition features Winchester's high-velocity powder charge that generates significantly higher muzzle velocities than standard buckshot loads. The 9-pellet 00 buck configuration provides an optimal balance of pellet count and individual pellet energy, creating a wider effective pattern than smaller shot sizes while maintaining superior penetration. Each shell undergoes rigorous quality control testing to ensure consistent performance across temperature extremes and storage conditions.

Key Features

• High-velocity powder charge delivers maximum muzzle energy and stopping power
• 9 pellets of premium 00 buckshot (.33 caliber) per shell
• 2.75-inch hull length fits all 12-gauge shotguns including 3-inch chambers
• Precision-formed lead pellets maintain consistent spherical shape for uniform patterns
• Heavy-duty brass base and reinforced hull construction prevents case separation
• Low-flash powder reduces muzzle signature in low-light conditions
• Temperature-stable propellant performs consistently from -20°F to 140°F

Field testing demonstrates tight, consistent patterns at defensive ranges with minimal pellet deformation upon impact. The high-velocity loading proves effective for home defense scenarios where immediate incapacitation is critical, while the 2.75-inch length ensures reliable cycling in semi-automatic shotguns. Law enforcement agencies have documented excellent barrier penetration through common building materials while maintaining controlled expansion patterns.
