A 7mm Remington Magnum is wayyy too much rifle for Florida deer.

The 4200 scope is also wayyyy over kill.

I doubt if you needed anything more than a .243 with a 3 x 9 x 40 Bushnell Banner.

How much meat do you think you are going to have left from a 90 pound deer when you hit it with that Mack truck of a gun that you have?
