First off, let me say that caliber/cartridge opinions are a little bit on the short side of your post here, in my mind. If you really are serious about trying to kill a deer at the ranges you talked about it's probably not gonna happen with an off-the-shelf rifle without some serious tuning, lots of handloading/load development, good glass, and lots and lots of practice at those ranges. It's not just a simple matter of picking up a couple of boxes of factory ammo and heading out there. Don't get me wrong....I'm not saying it can't be done, but it is done consistently by very few. Lots of time, effort, and money become involved in a quest like this. Perhaps I'm preaching to the choir here, and you may be already a competent, realistic handloader/ shooter. If so, I sand corrected. If you ever read some of Ridge Runner's posts on here, you will get a good idea of the tremendous amount of time and money it takes to become proficient at what you seek.
With all that said, any of the three cartridges you mentioned should do the job if developed correctly. I personally would give more of a nod to the 300 Win Mag and the 7mm Rem. Mag. JMHO.........
