She should be fine with that load. I shoot 80 grains T7 (loose) out of a .45 cal, and there is very little drop between 50 and 100 yards with the 200 grain Shockwave. I'm getting a bit more velocity than her because I'm shooting loose powder out of a .45, but that sounds about right. In fact, with my setup I'm only a couple inches low even out to 150 yards.

I took a deer cleanly at 150 yards last year with 80 grains of powder. 80 grains is more than enough for probably 90% of whitetail hunters.
