I am a bit experienced with firearms and know how to handle them. I take them out to the range and fire them. My friend is a hunter and recently gifted me with a SPENT 30-08 Springfield casing AT SCHOOL. Now in my school handbook it states:
It shall be a Class I felony for any person to possess or carry, whether openly or concealed, any gun, rifle, pistol, or other firearm of any kind, or any dynamite cartridge, bomb, grenade, mine, or powerful explosive on school property.
it also states that
Possessions, uses, or transfer of anything deemed as a weapon.
This is not classified as a weapon since the shell was ejected, the powder was burned, and the casing was deemed "Harmless".
I am asking this because my elementary school completely shut me down for having a bullet scale not behind powder or in a casing and they almost expelled me about 10 years ago if my grandfather hadn't stepped in.
I need an answer here to calm my father down. I live in the United States in South Carolina.
