Light weight - Fiocchi Defense Dynamics Low Recoil 12 Gauge 1 oz 2 3/4'' Slug Shotgun Ammunition

Got these slugs in and was surprised how light they felt. Haven't had a chance to shoot them yet but when I took one out of the box it felt empty though it obviously was not being that they are clear and you can see it from the side or just look in the end of the shell. But i'm guessing being lighter will also mean less recoil when shot, though to be honest was just getting them because they were cheaper, but am looking forward to seeing how they do.
