Quick Answer
When choosing ammunition for sea ducks, consider the bird's size, species, and hunting environment to select the optimal load weight, shot size, and choke constriction. A balanced load of 2 3/4" or 3" length with a lead or non-toxic payload is often preferred.
Choosing the Right Load Weight
For long-tailed ducks, a 2 3/4" or 3" load weighing 1 1/8 oz to 1 1/4 oz is a good starting point. This load length and weight provide sufficient penetration for the bird’s body and organs while minimizing damage to surrounding waterfowl. When hunting smaller sea duck species, a 1 oz load may be more suitable.
Shot Size Selection
Select a shot size that is large enough to penetrate the bird’s body effectively but small enough to minimize pellet dispersal and surrounding damage. For sea ducks, a #2 or #3 shot size is often preferred, as it offers an optimal balance between penetration and dispersal. However, shot size can vary depending on the hunting environment and the specific sea duck species.
Choke Constriction and Spread Pattern
When choosing a choke constriction, consider the hunting environment and the desired spread pattern. A modified or improved cylinder choke can help to maintain a tighter pattern at longer ranges, while an extra-full choke can produce a wider spread for closer shots. For hunting sea ducks, a modified choke with a 30 to 40 yard effective range is often a good starting point.
