I don't want to steal this thread but I am curious, what were the circumstances that soured you on the Creedmoor for elk? Things I'm curious about are shot placement, bullet used, distance shot, angle of animal when shot? IMO the Creedmoor is a great round but not necessarily a great elk round. I personally have never used my Creedmoor rifles for elk but have thought about it. I am generally of the opinion shot placement and using a good bullet are the most important aspects of a clean and ethical kill rather than cartridge power. If a person can shoot their Creedmoor accurately versus a .300 that they can't shoot I would say go with the Creedmoor. Just keep distances reasonable and use a good bullet. This information may help the OP decide between the two. Thanks.
