So I currently have and been shooting a Sport II. I am transitioning from sporting clays to hunting with it and just wondering what all if anything needs to be modified. Also plan on getting into waterfowl in the future as well. I know the design of the gun is sporting clays in particular so I am not sure if things such as the buffer spring would need to be replaced for a higher tension spring. Are the loads used for birds in general much greater than clays? As well as the gun being for 3" shells, can I stick with 3" for dove as well as waterfowl in the future?
