Developed by John Lazzeroni as the dangerous game capstone of the long-action series, the Saturn was built for professional hunters and serious African safari clients. It shares the Lazzeroni case with the Warbird and Galaxy but is necked out to .375 for maximum sectional density and penetration on elephant, Cape buffalo, and hippo.
