My one bolt rifle is a 30-06, but often I wished it had less recoil. My interest is mainly in practicing on paper. You should reconsider .243 win over a 30 cal option since you sound much more interested in practice than big game hunting. 223 is more economical for practice but handloading narrows that gap.
I am still glad I have more than a 223 bolt just in case.
