I’ve killed big game with the .223, 7mm Rem Mag, .300 WSM and .300 Win Mag.
I personally find the recoil difference between the 7RM and .300 Win insignificant. The .300 is more but it doesn’t bother me. It just feels different. The .300 WSM is more like the 7mm recoil wise.
I’ve killed the most game with a 7mm Rem Mag followed closely by the .30-06. If I were you I’d shoot them in similar rifles and see what your opinion is. Around here there is far more 7mm components than .30 cal in these times. I’d shoot a .300 with 180s if it was me hunting those things. Maybe 200’s if I did more Moose and Elk. 180 grain .30 caliber bullets at 3,000 FPS will be plenty for anything on your list.
