I am looking at buying a ruger super blackhawk hunter or a super redhawk in 44 mag. Does anyone have any advise??

I have shot a 44 mag before so I do know what the recoil is like. Used to go to the range with my brother shooting his old blackhawk.

Also I am going to buy a t/c encore next year in .243 or 7mm-08 for deer hunting also. Is the 243 good for 300 yards in the encore or would the 7mm-08 be better?? Thanks Dave
