Quick Answer
A 28 ga shotgun typically achieves patterns of 20-40 inches at 20 yards with field loads, and 10-20 inches at 20 yards with target loads.
Patterns with Field Loads
When using field loads in a 28 ga shotgun, the typical patterns achieved are 20-40 inches at 20 yards. This is due to the larger shot size and slightly larger pellet spread. For example, a 28 ga field load with a #5 shot will spread to around 24 inches at 20 yards. To achieve tighter patterns, use a choke that is 1/2 to 3/4 full.
Patterns with Target Loads
Target loads in a 28 ga shotgun produce tighter patterns, typically 10-20 inches at 20 yards. This is due to the smaller shot size and tighter pellet spread. For example, a 28 ga target load with a #8 shot will spread to around 12 inches at 20 yards. Use a full choke to achieve the tightest patterns with target loads. Keep in mind that target loads are designed for precision shooting at longer ranges, so it’s essential to adjust your aiming point accordingly.
Choke Selection
The correct choke selection is crucial in achieving the desired pattern with a 28 ga shotgun. A modified choke is suitable for field loads and provides a 24-28 inch pattern at 20 yards. A full choke is suitable for target loads and provides a 10-12 inch pattern at 20 yards. Avoid using a skeet choke as it will result in a too-open pattern, and a cylinder choke will result in a too-wide pattern.
