The Thompson/Center Contender pistol is renowned for its versatility, allowing shooters to swap barrels and calibers with ease. This adaptability extends to the .45 Colt/.410 bore combination, offering a unique blend of handgun and shotgun capabilities. However, understanding the nuances of the Thompson Contender 45/410 choke is crucial for optimal performance and safe shooting. This guide delves into the specifics of this versatile firearm, exploring choke options, ammunition choices, and practical applications.
Understanding the .45 Colt/.410 Barrel System
The Contender's .45 Colt/.410 barrel isn't simply a dual-caliber system; it's a testament to clever engineering. The .410 bore is typically integrated into the larger .45 Colt barrel, often requiring a specific adapter or interchangeable insert. This design maximizes functionality without significantly increasing the overall size and weight of the firearm. This combination allows for the use of both powerful handgun cartridges and versatile shotshells, extending the weapon's applicability significantly.
Choke Tubes and Their Impact on Shot Patterns
The choke tube in a .410 bore barrel is critical for controlling the shot pattern. Unlike larger shotgun gauges, the .410 has a smaller bore diameter, making choke selection even more impactful. While not all .45 Colt/.410 barrels feature interchangeable choke tubes, those that do usually offer options such as:
- Improved Cylinder: Provides a wide shot pattern, ideal for close-range shooting where a large spread is necessary.
- Improved Modified: A balance between range and pattern density, suitable for medium-range targets.
- Improved Full: Delivers a tighter pattern, extending effective range but at the cost of a smaller spread.
The choice of choke tube significantly influences the effectiveness of the firearm when using .410 shotshells. Careful consideration of the intended use (e.g., small game hunting, pest control, or self-defense) is paramount.
Ammunition Considerations for Optimal Performance
Using the correct ammunition is crucial for both accuracy and safety with a Thompson Contender in .45 Colt/.410.
.45 Colt Cartridges:
The .45 Colt is a powerful cartridge known for its versatility and stopping power. A wide variety of ammunition is available, including:
- Full Metal Jacket (FMJ): Suitable for target practice.
- Hollow Point (HP): Designed for increased stopping power in self-defense situations.
- Soft Point (SP): Offers a balance between expansion and penetration.
Choosing the right ammunition type depends on the intended application. Always check the manufacturer's specifications for safe and proper use.
.410 Shotshells:
The .410 shotshell options present further considerations:
- Shot Size: Shot size (e.g., #4, #6, #8) affects range and pattern density. Smaller shot sizes are better suited for small game, while larger sizes are more effective at longer ranges.
- Shot Type: Different shot types (e.g., lead, steel, bismuth) have varying characteristics concerning penetration, range, and legality. Always comply with local regulations on ammunition usage.
- Slug Rounds: .410 slug rounds can be surprisingly accurate at medium ranges, making the Contender suitable for larger game hunting (within ethical hunting guidelines and legal regulations, of course).
Practical Applications and Considerations
The Thompson Contender 45/410's unique combination of calibers opens up a vast array of practical applications:
- Small Game Hunting: The .410 bore excels in this area, with the right choke and shot size proving effective for rabbits, squirrels, and other small game.
- Pest Control: The versatility allows for different approaches to pest control, depending on the size and distance of the target.
- Self-Defense: The powerful .45 Colt provides effective stopping power, while the .410 offers the option for a wider spread of projectiles in close-quarters situations.
- Target Shooting: Both calibers are suitable for target practice, allowing for skill development in handgun and shotgun shooting.
