If you are a fan of single shot rifles, the Ruger #1 is the rifle you want. The Tropical models, at one time anyway, seemed to have the best wood. Chances are that the butt stock will be unevenly bedded and will split the tang in short order, so you might as well have it bedded properly right away. If you decide to scope it, the #1's quarter rib will set the scope too close to your eye for the .458's recoil, so you might want to consider other options for mounting the scope if you go that route. I mounted a 1.5-5X Leupold so the ocular was even with the front face of the falling block. I could only use up to 3X because of the long eye relief, but this was not a problem, and the advantages of not being hit by the scope with the recoil of a powerful rifle and having nothing over the loading port out weighed the dubious disadvantage of not being able to use the scope through it's full magnification range
In a repeater I like the CZ for a number of reasons, not the least of which is the generous magazine capacity. The Ruger 77 is a pretty rifle, but like I was told back in my over the road days when I #####ed about the ugly truck I drew "Pretty don't haul freight!" The CZ has a serious look that the Ruger doesn't capture, although this is a strictly personal impression. I once had a Whitworth .458 that was stocked in a beautiful piece of wood, was deep blued, had the famous Whitworth 3 leaf express sight. It was light and delicate and it hurt my feeling to take that rifle outside. After a year or so of using the .458 I had the opportunity to swap it for a beat up 602. The pretty Whitworth looked like a toy beside the business like Brno. I swapped it straight across and immediately (without shooting it) sent it out for some refinements to suit my needs. A couple of years later it had metamorphosed into the best rifle I have ever owned. So yes, I am a CZ fan.
