I have a Fireball that shoots better than I deserve, I don't think it's ever shot a group of five over 3/4", with any bullet under 52gr. I don't see anything heavier being suitable for the case capacity, so I haven't tried them. It's a seriously well-balanced cartridge, but so is the Deuce. I like them both, but I have a couple .204s that electrocute coyotes, they are pretty decisive, but might be too loud for nearby houses.
