It was rammed really hard, so I think it might be a .577 Cal. gun it was fired out of. Really tough question, but do any of you know what kind of Civil War musket this was fired from?
Your hard-rammed .58 civil war yankee-styled 3-groove .58 Minie-bullet has 3 wide rifling-groove marks on it, so I believe it was fired from a US .58 Springfield Rifle-musket. So, your bullet wasn't too large for the rifle's bore... the bore had become very "fouled" with gunpowder ash & bullet-lube grease (that's what the bullet's body-grooves are for) from firing all day without being cleaned.
