RE: 7mm Remington Mag - QUESTION!
Your best bet with keeping the 7mag is a double lung to stay back from the meat. That or a head shot which I have heard vary mixed reviews on. Maybe try the reduced recoil, but really unless your needed to reach out there(like 300yrd+ shots consistently) why not do something in the .243 to .270 caliber range? personally if I didn't live in the never ending west I would be shooting iron sights and a lever gun most of the time.
