A modified 2-star barrel on a Browning shotgun is designed to create a tighter shot pattern compared to a cylinder or improved cylinder choke. This modification allows for a more focused spread of shot, making it ideal for medium-range shooting situations, such as upland bird hunting or clay target shooting. The tighter pattern helps improve accuracy and effectiveness at longer distances by concentrating the shot in a smaller area.
