For a magnum-sized action, CZ seems to one of few options. One of the models has a pop-up aperture sight in the bridge. The dovetails that allow direct scope ring attachment seem like a plus, esp for hard kicking calibers. Single set trigger. I find the stocks low with medium rings. The magazine box shell has flutes, and the follower has notches to clear them - at least on the 6.5x55 models. They look as if they might prevent cartridges from sliding forward on recoil, whether to aid cartridge feed, or keep bullet tips pointed - for cartridges with enough shoulder. Bolt movement is rough on new ones, anyway. CZ does not chamber short mags as far as I know.
The couple of FN M70's that I handled were well finished and operated very smooth. As others point out M70 is lighter than 550. M70 in .264 Win Mag may be my next purchase.
Ruger's new .375 and .416 allow them to get around need for a magnum-sized action.
