I have over 40 years of elk hunts behind me as a hunter and as a guide.
I would say without hesitation, use a 120 grain Nosler Partition, a 115 Grain Barnes or a bonded bullet of 110 grains or more.
Skip all the rest. Not that all others are bad, but none of them are as good as the bullets above for what you will be doing.
ESPECIALLY skip anything made by Burger.
They have a VERY VERY high failure rate even on deer and antelope.
Back when they first came out I would have fully agreed with you, but reports of late show very different tale.
Since I can't seem to get any 6.5mm 147 ELDs right now, I will be elk hunting this fall with the 6.5mm hunting VLD, and have no worries.
