Either of your loads will kill any whitetail that ever lived if you hit them in the heart/lung area...I use hard cast 200 grain SWC's at 1230 fps and I have never had a deer shot with one go over 30 yards...I would NOT shoot a hard quartering away shot using the super because I simply do not have a bullet that has enough sectional density and energy to penetrate a long way like a good heavy hard cast swc in a .44 mag but at any reasonable angle the Super will do the job.
