Shotgunners used to scoff at the notion of mounting a scope on a slug gun. The slug's effective range was short, and snap-shooting was routine. The reason many deer hunters now choose scopes is because modern slug guns are more accurate and capable of taking game at ranges once considered improbable. Scopes are more accurate than irons at all ranges and, believe it or not, faster even up close. With a scope, the target and reticle appear in one plane, both tack-sharp. Paste the reticle where you want to hit, and shoot. For long pokes, the scope allows you to see targets in detail and shoot a shade high with precision. Modern shotgun scopes weigh just half a pound or so and deliver bright images. Forget about fogging and mechanical failure. Reticle choices, including illuminated versions, abound. All told, a scope is probably your best slug gun sight.
