I have a CZ 550 safari classic or classic safari, can't remember the order of the two words on the action. I do remember that it has open sights, leaf flip ups, and a single set trigger. It is buried in a safe as I have two heym bolt guns in the same caliber, .375 H&H. I enjoy shooting the heyms and have never had an issue, but my Africa trips lean toward double rifles. Might sell the CZ but haven't given it any thought until now.
