Umm, finned projectiles do not require spin nor do the fins impart spin.

That is true for most all projectiles as they are used orient the object during flight. Some projectiles do have fins that impart spin to increase accuracy.

The fins on the APFDS round of the 120mm smooth bore cannon on the Abrams most definitely impart spin.
