Your thinking is similar to mine but I went all the way to 6.5 WSM to get a little more velocity and energy. 140’s in the 3200 fps realm is quite an impressive long range round to me and the PRC isn’t far behind. No flies on the creedmore as it’s a great round for sure but for the slightly increased recoil I will take a bit more speed.
Mine is a bit chunky weight a tad over 9# but over 2 lbs of that is the Kahles K624i on top. With the break on the barrel I am quite sure the recoil is about like my old light weight 243 was.
