Other than you are a one gun man with a bigger caliber, why would you ever feel the need to use anything bigger than a .243 Win for whitetail?
Because .30/30s are easy to carry and fun to shoot?
Actually, I switched to .270s a long time ago, because my .243 experiences weren't good (maybe bad bullets?), but this spring I picked up a .30/30 to mess with, and plan on using it this fall.
