I get the general Cabela inventory page. Can’t keep searching. It seems that the switch-off barrels and chokes have very limited ballistic advantages. People use shotguns for devastating, up-close stopping power, and people use rifles for accuracy at great distances. Slugs are a poor cousin to the Minie ball-shaped bullet. They’re heavy and have poor aerodynamics, and close up you have to aim them, which you don’t need to do with shot except very generally.
