My grandfather knew a guy who hunted deer with rifled slugs from a 410 (back in the ol days when it was legal)
About the same performance as a 40cal roundball from a muzzleloader. The 410 is legal in some states and is used quite well if shots are close. Inside traditional bow hunting range i see no reason why it wouldnt work well if you took broadside double lung shots. Yes theres better options but a 40cal hole before expansion thru both lungs is going to leave a mark that a bandaid cant fix
