I didn't pre-read the Jack O praises as an endorsement for the 270 caliber before owning one. If my Winchester had been an 06, rather than a 270, I would perhaps be speaking 06 praises today. As mine was found to be a 0.277" barrel on a Classic Featherweight frame (what do you know - there IS an 06 in Featherweight), I put my hands on the first available SCOPED RIFLE, a 270 Winchester, and never let go.
I won't be departing the South to hunt elk, caribou, rams, or bears. My 270 fits my local need for hunting deer and hogs. I cannot be convinced by bc, choices in ammo, bullet weights, or other caliber comparators, which I never experienced. I'm all in for the 270. For me, there is no further discussion.
Buy what you like, what is available, what you can lay your hands on, what makes you confident, and make that one gun your right hand - regardless of caliber.
