Hello, when I am calmer someone comes and upsets me. The fact is that an acquaintance offers me a change. His Winchester 70 Pre 64 in 416 Remington Magnum for my Ceska 550 Safari Magnum in 458 Lott. He says he has 3 rifles in 416 and none in 458. The Winchester is a great rifle but I love my Ceska and the 458 Lott strikes me as a more serious cartridge than the 416 RM. What do you think? Take care.
