It’s a really tough call because everything is so subjective. What’s best for me, may not be best for you. For me personally, the creedmoor would more fit the bill for what you described. To build a rifle in a magnum caliber that would be comfortable to shoot for long periods of time target shooting would be way to heavy to hunt with. The affects of recoil on a shooter are cumulative, and add up, causing a person to shoot worse whether they realize it or not. A soft kicking round, like the creedmoor, could be made light enough to hunt with and still be good for sustained shot strings for target shooting. Years ago I did all of my long range target work with a 13lb rifle chambered in 6-284. That was perfect for me.
