You certainly don't need a fancy bullet to take a whitetail, but with your ranges and the speed the 7 Mag can generate a tougher bullet wouldn't be bad. Of course you could load it down since you say the majority of your shots rarely exceed 100 yards. Then you could easily get by with a less expensive bullet. Hornady Interlock and Winchester Power Point come to mind. There are many others.

I have shot 2 deer with the 120g NBT out of a .284 Win. The first a whitetail buck at 35 yards. Took his heart out, but did not exit. The jacket was perfectly mushroomed, but there was no core left. The 2nd a mule deer doe at 281 yards. The bullet glanced off her shoulder carried on through the neck and exited her head. MV was 3200 FPS.
