There are so many rifles out there that will fit your purpose. Like mrbb stated, I'm not sure why you are only considering these models. Check out as many as you can before you "pull the trigger" and see what one fits you best and feels the best in your hands. CZ are nice but so are Brownings, Tikkas (my favorite) and Sakos among others. Any chambering from .243 on up to 30-06 will do the job. Mags are not required and for deer and antelope my choice would be any of the sub 30 calibers. (243, 6mm, 7mm, 6.5mm)
