I agree with Bogey,,, my favorite "open country" whitetail cartridge is the .243 Winchester. Light recoil, amazing accuracy, outstanding for long range shooting and packs the punch to take out whitetails easily. The other thing I like about the .243 is that it is also an outstanding long range varmint/predator cartridge (woodhchucks, coyotes, etc) not to mention an outstanding caliber for pronghorn antelope and such. I shoot the other calibers mentioned as well, but the Winchester rifle I have that is chambered for the .243 Winchester is the one I take out of the safe when I'm hunting whitetails in open country and she's never let me down.

I'm not knocking the other calibers mentioned,,,, they're good as well and will do the job for you,, I just really love my .243
