That’s impressive from a 127gr bullet!My wife just took a 44 inch bull moose with her 6.5CM using 127gr Barnes LRX. That's her second moose with that bullet from her 6.5 so I would assume it would work well for elk too. The 6.5's have a great sectional density allowing them to perform better than a lot of people are willing to give them credit for. I say take your Creedmoor and go enjoy your hunt with confidence.
