A thin jacketed bullet like a Berger wouldn't be my choice but I wouldn't hesitate to kill a moose with a 6.5 prc loaded with a good copper bullet like Barnes, Hammer or CEB. My wife keeps putting moose on the ground with her little creedmoor using 127gr LRX. I would imagine a prc would do it even better. Moose don't always give broadside shots and there is a lot of muscle and heavy bone up front, so use a better constructed bullet. With big critters, a bullet's terminal performance is way more important than a higher b.c. in my opinion.
