Spin is only one way to stabilize a projectile. The Abrams Tank fires its projectiles down a smooth bore. Some of those projective are actively stabilized with some type of guidance system but many of the projectiles are passively stabilized. The sabot kinetic energy penatrator round is fin stabilized. The HEAP rounds also are fin stablized and they have very small fins relative to the KE rounds. All of these round can be fired very accurately out to sever thousand meters. Now a 120mm projective has a serious BC when compared to a 12 slug but it always amazes me that some slug manufactures have not tried to create a fin stablized sabot slug for a 12 gage. Especially with the avalibility of the longer 3 1/2 inch cases would make it easier to make a fin stabilized slug that was long and thin enought to fly stable but still have enough mass to be an effective deer projectile.
Sorry that is off topic but it sort of jumped into my mind.
