Don’t use range ammo as self-defense ammo. There are a number of good reasons why it’s a bad idea.
Range ammunition — meaning full metal jacket or fragmenting ammunition in center fire rifles and pistol, target or bird shot in shotguns — is a generally poor self-defense ammunition choice. Not that there aren’t good uses for it (ie the range, the dove field), but ammunition is a tool and you should use the right tool for the job.
