Go with the Shortmag. From 160gr partitions, down your gold with factory barrel twists etc. There's new bullets out there that go to 165-170gr (Matrix) that blow 7mms out of the water if you have a fast enough twist to stabilize em'. Watch bigngreen's 800+ yd Elk video if you want visual proof.
Plus no belt on the case. I love mine.
The 264 was a neat idea, & performed well, but, compared to the 270 wsm..... Not gonna win, in my opinion. The 270 wsm gets my vote.
Whenever Elk are involved, especially at distance, my personal minimum is a 270.
