.....I never understood the logic behind the places where shooters were limited to slugs or muzzle loaders....
I do live in one of those states, the reasoning is that close proximity of home/farm buildings, flat landscape, and livestock-vs-terminal range of necked cartridges, (which can be up to 7 miles).
This is how Iowa's regulations read....
PROHIBITED HUNTING NEAR BUILDINGS
You cannot discharge a firearm, or shoot or
attempt to shoot, a game or furbearing animal
within 200 yards of a building inhabited by people
or domestic livestock or a feedlot unless
the owner or tenant has given consent to do
so. Feedlot means a lot, yard or corral where
livestock is confined for the purpose of feeding
and growth prior to slaughter. Pastures, hayfields
or cropfields where animals are allowed
to graze are not considered feedlots.
Regarding roads....
Private Property Highway or Right-of-Way Fence Ditch Roadway (includes shoulder) SHOOTING RIFLE OVER WATER OR HIGHWAY.
You cannot shoot any rifle on or over any
of the public highways or waters of the state
or any railroad right-of-way. You cannot discharge
a shotgun shooting a slug, pistol or
revolver on or over a public roadway.
Additionally, no person shall discharge a rifle,
including a muzzleloading rifle or musket, or a
handgun from a highway; or discharge a shotgun
shooting slugs from a highway north of U.S.
Highway 30, while deer hunting.
“Roadway” means the portion of the highway
improved, designed or ordinarily used for
vehicular travel, including the shoulder.
“Highway” means the entire width between
property lines, from fenceline to fenceline (includes
the ditches).
Short answer to the OP, every state is different, know the laws, use common sense, know your target and what is beyond.
