Quick Answer
For 40-yard shots with 00 buckshot, use a pattern with a spread of 18-22 inches to ensure a lethal hit. This range allows for a tight enough pattern to penetrate vital organs. Shotguns with a choke tighter than Modified may not provide enough spread.
Choosing the Right Pattern
When it comes to buckshot patterns, the goal is to create a spread that covers a large enough area to hit vital organs while minimizing the risk of non-lethal penetration. For #00 buckshot at 40 yards, a pattern with a 18-22 inch spread is ideal. This range allows for a tight enough pattern to penetrate vital organs, increasing the effectiveness of the shot.
Optimal Choke Settings
To achieve the desired pattern, a shotgun with a choke tighter than Modified may not be the best choice. A choke in the Improved Modified or Full range (1.5-2 inches tighter than cylinder) is more suitable for buckshot patterns at medium ranges. This choke setting will provide a larger pattern and better penetration, making it more effective for hunting deer.
Pattern Comparison
To give you a better idea of the optimal pattern for #00 buckshot at 40 yards, consider the following examples: Remington’s 870 with a 18-inch spread at 40 yards, or a Mossberg 500 with a 20-inch spread. These patterns are achievable with the right choke and ammunition combination. When selecting a shotgun and ammunition for deer hunting, consider these specifications to ensure you’re getting the best possible pattern for your shot.
