I have had my 3rd neck surgery and will need to lessen recoil going forward.  I am mainly concerned with antelope and Mule deer.  I own a .243 and a 7MM Rem Mag currently.  Would I be better off shooting reduced recoil rounds through the 7mm Rem Mag or purchase a different caliber?  I think the .243 would suffice for antelope but may be pushing it for a big mule deer.  Any thoughts?
