Understanding your shotgun choke is crucial for achieving consistent accuracy and optimal performance. While many modern shotguns rely on threaded choke tubes, many older models and some newer ones still utilize fixed chokes identified by notches. This guide will delve into the world of shotgun choke chart notches, explaining how they work, how to interpret them, and how to choose the right choke for your shooting situation. We'll cover everything from identifying the notches to understanding the pattern differences they create. This knowledge will significantly improve your shooting accuracy and overall enjoyment of the sport.
Understanding Shotgun Choke Types and Their Purpose
Before diving into notches, let's quickly recap the function of different shotgun chokes. The choke tube (or fixed choke) constricts the diameter of the barrel at the muzzle. This constriction affects how tightly the shot pattern spreads.
- Full Choke: Produces the tightest pattern, ideal for long-range shots at flying game like ducks or geese.
- Modified Choke: Offers a good balance between range and pattern density, suitable for a variety of hunting scenarios.
- Improved Cylinder Choke: Provides a wider pattern, best for close-range shots or situations where a wider spread is advantageous, such as hunting in thick cover.
- Skeet Choke: A very open choke, delivering an extremely wide pattern ideal for skeet shooting.
- Cylinder Bore: The most open choke, with no constriction. Provides the widest pattern.
These are the most common choke types, but variations exist. Manufacturers might have slightly different names or designations for these constrictions. However, the basic principle remains the same: tighter constriction equals tighter pattern.
Decoding Shotgun Choke Notches: Your Visual Guide
Fixed chokes, identified by choke notches, offer a visual system for identifying the choke type. The number and arrangement of notches are the key. Unfortunately, there's no universally standardized system across all shotgun manufacturers. Therefore, always consult your shotgun's manual for the definitive choke identification chart specific to your firearm model.
However, some common patterns exist:
- One Notch: Often indicates a Full Choke.
- Two Notches: Frequently represents a Modified Choke.
- Three Notches: May signify an Improved Cylinder Choke.
- No Notches: Could indicate a Cylinder Bore or an Improved Cylinder.
Important Note: These are just common trends. The notch system can vary significantly between manufacturers (e.g., Remington, Winchester, Browning). The only reliable method for knowing the exact choke is to cross-reference the notches with your specific gun's manual.
Example: Identifying Choke Notches on a Remington 870
Let's imagine you own a Remington 870 shotgun. Its manual might state:
| Number of Notches | Choke Type |
|---|---|
| 1 | Full Choke |
| 2 | Modified Choke |
| 3 | Improved Cylinder |
| 0 | Cylinder Bore |
This table would be your go-to reference for identifying chokes on your specific Remington 870. Trying to rely on a generic chart could lead to mistakes.
The Impact of Choke on Shot Pattern: Visual Representation
The following illustration demonstrates how different chokes affect shot patterns. Note that the actual pattern size will vary based on shot size, load, and the specific shotgun.

Choosing the Right Choke for Your Hunting Situation
Selecting the appropriate choke is critical for success. Consider these factors:
- Target Distance: Longer distances require tighter chokes (Full or Modified).
- Game Type: Smaller, faster-moving game (e.g., doves) might benefit from a more open choke (Improved Cylinder), while larger, slower targets (e.g., geese) usually call for tighter chokes (Modified or Full).
- Hunting Conditions: Thick cover necessitates a wider pattern (Improved Cylinder or Cylinder Bore), while open areas allow for tighter chokes.
Table: Choke Selection Guide (General Guidelines)
| Game Type | Distance | Recommended Choke |
|---|---|---|
| Ducks | Long | Full, Modified |
| Geese | Long | Full, Modified |
| Quail | Short-Medium | Modified, Improved Cylinder |
| Doves | Short-Medium | Improved Cylinder, Modified |
| Trap Shooting | Short | Improved Cylinder |
| Skeet Shooting | Short | Skeet, Improved Cylinder |
Disclaimer: These are general recommendations. Always practice and fine-tune your choke choice for optimal performance.
Conclusion: Master Your Shotgun Choke Notches
Understanding your shotgun's choke system, especially if it utilizes notches, is paramount for accurate shooting. Remember that manufacturer-specific charts are the ultimate authority for interpreting the notch system. By understanding the relationship between choke constriction, shot pattern, and hunting situations, you'll significantly improve your shooting skills and hunting success. Always consult your firearm's manual, practice with different chokes, and adjust your approach to match the specific conditions you encounter.
