I think the 270 is a great elk gun; if you've got one your comfotable with why not use it? That B&C reticle seems geared toward long shots which is something I'm not in favor of. Most people shooting game at long distances haven't taken the time to practice at those ranges and the results aren't always pretty. If you want to take long shots at elk I'd move up to one of the 30 calibers and practice a lot.
