It depends!
What bullet you use dictates said bullets Ballistic Coefficient.
What are your requirements regarding kill zone?
The .72 is defenetly out for you as bullets that large has a BC like a grand piano with the lid up!
The .58 can get decent bullets, in the 600-700grain range. A WAG would be in the.27-.30 range.
Lets say .30 and 970fps for a 700grain bullet.
Given a 8" kill zone you have a point blank range of 84yards sighted zero at 70 yards.

TOF = Time Of Flight
OGW = Optimal Game Weight
Trajectory like a rainbow with these big slow bullets, no way around it.
Now you're confused at a much higher level ;-)
