I assume that you ultimately intend to hunt deer with these loads? If so, I advise looking for bullets in the lower-middle end of the weight range. Deer are not hard to kill, speed will be more helpful than momentum. Sometimes, the lightest bullet you can get will have the flattest trajectory at practical ranges but usually it's something on the low-average side.
This is why you need QuickLoad, it gives you some grounding for your quest.
I'll play around a little and see what it says....
