Winchester Invector-Plus 12 Gauge Full Choke Tube: Master Your Shot Pattern

For serious shotgunners, hunters, and competitive shooters, achieving consistent, dense shot patterns is paramount to success. The quality of your choke tube can make all the difference, transforming near misses into decisive hits. The Winchester Invector-Plus 12 Gauge Full Choke Tube (MPN: 613051), crafted from durable 17-4 Stainless Steel, is engineered to elevate your shotgun's performance, ensuring unparalleled accuracy and range.

The Pursuit of the Perfect Shot: Why Choke Tubes Matter

If you've ever wondered how to tighten your shot groups, extend your effective range, or simply achieve more consistent results with your 12 gauge shotgun, the answer often lies in understanding and optimizing your choke tube. A choke tube is a constricted device that screws into the muzzle end of a shotgun barrel, designed to control the spread of shot as it leaves the barrel. Different constrictions are suitable for varying distances and types of game or targets.

The primary problem a high-quality choke tube solves is the inconsistency of shot patterns. Without proper constriction, shot can spread too quickly, leading to "holes" in the pattern where pellets are sparse, or a pattern that is too wide to be effective at desired ranges. This means less energy delivered to the target and a lower probability of a clean, ethical take or a broken clay.

Unlocking Superior Performance: The Invector-Plus System Advantage

The Winchester Invector-Plus system is not just another choke tube; it's a meticulously designed component engineered to work in harmony with your shotgun's barrel. What makes the Invector-Plus system stand out?

• Synergy with Back-Boring: Many modern Winchester shotguns feature back-bored barrels, which means the internal diameter of the barrel is slightly larger than standard. This reduces friction on the shot column, leading to higher velocities and less pellet deformation. The Invector-Plus choke tubes are specifically designed to complement this back-boring, creating a seamless transition that further enhances pattern consistency and density.
• Longer Choke Taper: Unlike shorter, more abrupt choke tapers found in some systems, the Invector-Plus boasts a significantly longer internal taper. This extended, gradual constriction allows the shot column to compress more smoothly and uniformly. The result? Fewer "fliers" (individual pellets that stray far from the main pattern) and a remarkably consistent, tight pattern with more uniform pellet distribution. This translates directly to increased confidence in your shot, knowing that more pellets are on target.
• Gas Sealing Innovation: A critical, yet often overlooked, feature of the Invector-Plus design is its ability to virtually eliminate gas blow-by. Gases slipping between the choke tube and the barrel can cause several issues:
  • Damage: Over time, high-pressure gases eroding the metal can damage both the choke tube and the delicate lands and grooves of the barrel, leading to premature wear.
  • Inconsistency: Gas escaping can disrupt the shot column's stability, contributing to erratic patterns.
  • Reduced Velocity: Energy loss from escaping gases can slightly reduce muzzle velocity.
  The Invector-Plus system minimizes this, ensuring that maximum energy is directed behind the shot column, preserving your equipment and optimizing ballistic performance.

The Full Choke: Precision for Distant Targets

The Winchester Invector-Plus 12 Gauge Full Choke Tube is classified as a "Full" constriction type. What does this mean for your shooting?

• Tightest Common Constriction: A Full choke provides the tightest constriction among standard interchangeable choke tubes, with a specific constriction diameter of .030 inches. This extreme narrowing of the barrel at the muzzle forces the shot column into a much denser pattern.
• Optimal for 40+ Yards: This choke is specifically recommended for shots beyond 40 yards. When hunting turkey across an open field, pursuing elusive waterfowl at long ranges, or engaging distant clay targets in a trap shooting scenario, the Full choke delivers the necessary precision.
• Maximizing Pellet Count on Target: By keeping the shot together for a longer distance, the Full choke ensures that a maximum number of pellets impact the target within a small area, which is crucial for delivering sufficient energy for a clean kill or a definitive break.

When to Reach for Your Full Choke: Real-World Applications

• Turkey Hunting: This is arguably the most common and vital application for a Full choke. Turkeys are notoriously tough, and a dense pattern of heavy shot (like #4, #5, or #6 lead shot) to the head and neck is essential for an ethical harvest. The Full choke ensures that your pattern delivers a concentrated blow at typical turkey hunting distances.
• Long-Range Waterfowl Hunting: While Modified or Improved Modified chokes are often preferred for decoying birds, a Full choke becomes invaluable when pass-shooting geese or ducks that are flying high and wide, beyond typical ranges.
• Trap Shooting: For the single targets presented in trap shooting, especially at longer handicap yardages, a Full choke can provide the dense, far-reaching pattern needed to consistently break clays thrown at speed.
• Predator Control: For dispatching coyotes or other medium-sized predators at longer shotgun ranges, a Full choke can help ensure sufficient pellet density with larger shot sizes.
• Upland Bird Hunting (Specialized): While not typically the go-to for flushing birds, a very experienced hunter might opt for a Full choke when specifically targeting pheasants or grouse that are known to flush far out.

Built to Last: The Power of 17-4 Stainless Steel

The material from which a choke tube is made is critical for its durability and performance. The Winchester Invector-Plus Full Choke Tube is constructed from 17-4 Stainless Steel. Here’s why this is a superior choice:

• Exceptional Strength and Hardness: 17-4 PH (precipitation-hardened) Stainless Steel is renowned for its high strength and hardness, making it incredibly resistant to the extreme pressures and forces generated by firing a shotgun. This ensures the choke tube maintains its precise constriction over thousands of shots.
• Corrosion Resistance: As a stainless steel alloy, 17-4 offers excellent resistance to corrosion, rust, and pitting. This is especially important for shotgun accessories that are often exposed to moisture, gunpowder residues, and harsh outdoor environments. Its robust nature means less worry about degradation and more time focusing on your shot.
• Durability and Longevity: This material choice contributes directly to the choke tube's long lifespan, providing reliable performance season after season. You can trust that your Winchester choke will stand up to the rigors of hunting and competitive shooting.

Maintaining Your Winchester Invector-Plus Choke Tube

To ensure your Winchester Invector-Plus choke tube continues to perform at its peak and to extend its lifespan, proper care and maintenance are essential.

• Regular Cleaning: After each shooting session, remove your choke tube from the barrel. Use a soft brush and a good quality bore cleaner to remove all gunpowder residue, lead fouling, and plastic wad remnants. Pay close attention to the threads on both the choke tube and inside the barrel.
• Lubrication: Before reinserting the choke tube, apply a thin layer of anti-seize grease to the threads. This prevents the choke from seizing in the barrel due to heat expansion and carbon buildup, making it easier to remove next time.
• Inspection: Periodically inspect your choke tube for any signs of damage, such as nicks, dents, or bulging. If any damage is present, replace the choke tube immediately. A damaged choke can negatively affect patterns and even be unsafe.
• Proper Installation: Always ensure the choke tube is screwed in completely and snugly by hand, then tighten with a choke wrench until firm. Avoid over-tightening, as this can damage the threads.
