Main problem some folks seem to have, me included, is managing the drop. It is rather dramatic because the friction of the air passing over the bullet's "rifling" , which is what causes the bullet to spin so that it remains on line,eats up energy that would other wise have been retained in the velocity of the bullet.(It is a Newtonian physics conservation of energy thing.) But with practice at the range, managing this isrelativley easy to learn.
Actually "rifled" foster style slugs out of a smooth bore shotgun do not spin. They get their stability from their weight forward designmuch like a badminton shuttlecock. It's the old "rock in a sock" theory. If the front is heavier than the rear, it can never catch up, which is what keeps it from tumbling. They have so much drop because of their relatively heavy weight, slow speed and huge frontal area. They are very inefficient from a ballistics standpoint.That having been said, they kill like the Hammer of Thor at the relatively short distances they are intended to be used at. I have literally knocked deer off of their feet with a well placed shot.
