I'm making perfect sense you're just not understanding, or don't care to understand. The point is that caliber isn't as important as bullet construction. Of course you can shoot cup and cores from any cartridge, but the point is that smaller calibers with frangible style bullets will create more damage than larger calibers with mono bullets, which defies the idea that "bigger=better." Yes, a 212 ELD-X from a 300 PRC has more bullet to do work than a 143 from a 6.5 creed or PRC, but is that "more" or "extra" necessary? Probably not. And this coming from someone who has killed bulls with a 300 PRC, I own one, love it, I also just killed 2 fine whitetail bucks with a 22 Creedmoor and 80 grain ELD-M's at 408 and 376 yards and broke both shoulders on both deer, and they were DRT. I know this is an elk discussion so I digress. Will monos kill? Yes. Will big calibers kill? Yes. No one is arguing that. But are big calibers required to kill elk consistently? No I don't think they are. Bullet construction, shot placement, impact velocity.
