Iowa law requires slugs if you are hunting deer with a shotgun, as well as single projectiles for any other firearm that is allowed for deer hunting, e.g., muzzle loaders, specified handgun cartridges and center fire rifles .24 caliber or larger.

It is my understanding that Iowa deer are much larger than Alabama deer.

I never shoot for the head or neck unless I am standing over a live deer that has already been shot.
