I shopped the last two years for a bigger DGR than my 375h&h. After looking at everything available, I settled on 404 Jeff. Then the search began for specific rifle finally settling on the Heym Express Martini. It's pricy but less than a custom rifle and Ralf Martini is one of the best in the business. Heym's engineering and machining is second to none and the rifle cycles ammo flawlessly as fast as you can work the bolt. My final decision rested on shooting both 404 and 416 Rigby side by side in same model rifles. Both are great calibers, but the 404 won out for following reasons: 1) very easy to reload ammo; 2) can be loaded to match Remington 416 performance and almost 416 Rigby performance; recoil was lighter on the 404 and more comfortable for me; ammo is less expensive (even though I reload). In final analysis, both are great calibers and you can't go wrong with either. As a post script, if cost is a big consideration, I would not hesitate with the CZ. They make a great rifle.
