From the chamberings you listed there is no doubt that the 270 (win) is the optimum choice. IMO regardless of what the list included - the 270 Win is an ideal deer cartridge. There are many other good cartridges out there. But after shooting close to 50 deer with the 270 from point blank to 400+ yds the 270 has never failed me. I shot deer with various other chamberings but the 270 is my pet.
