Doesn’t the 458 Lott also chamber and shoot the 458 Winchester?
Unless you are over run with rampaging elephants, 458 Winchester should get you buy short term.........
Wiki says the case is a blown out 375 H&H case
Don’t know if that helps
Also somewhere was an article critical of Guns and Ammo hyping the cartridge due to Jack Lott being
one of their writers. The consensus was it wasnt that big of an improvement over a 458 Winchester
