The choke you use depends on your target rather than the type of shotgun. For example: if you are shooting skeet, you would use improved or modified cylinder, but if you are shooting trap, you would use full choke.
It is not recommended to shoot slugs with a power pack chock on a JC Higgins model.

The Ithaca Model 87 shotgun typically uses interchangeable choke tubes to control the spread of the shot pattern. The specific choke tubes used on a Model 87 can vary depending on the manufacturer's specifications. Common choke tube options for the Model 87 may include Full, Modified, Improved Cylinder, and Cylinder chokes, allowing shooters to adjust their shot pattern for different hunting or shooting situations. It is important to refer to the owner's manual or contact Ithaca customer service to determine the correct choke tube options for the Model 87.
You will need to identify the manufacturer of the gun since JC Higgins was a Sears brand for guns they sold.
