I do not know your scope or your reticle.I can describe a reason I set up a rifle for hold under.
I was going hunting with a 1903A4 Springfield clone that has a 2.5 X Lyman Alaskan on it.The reticle is a post with a 4 MOA wide top.
I was satisfied prone with a sling and cheating with my backpack I shot a couple of less than claybird size 3 shot groups at the 350 yd max of the range.
Based on Nightforce software in a Dell palm pilot,I came up with this:

OK,it did not cut/paste too well,but column 4 is elevation in inches,not MOA.Column 5 is windage in inches.
This is for a 400 yd zero.Had I sighted in closer,like 200,I would be raising that fat post up to cover my target,and my eyeball would get crazy.
But note,out to 350 yds,I had to only make minor hold adjustment,like 3 in max,to just making a 6 oclock hold on the lower edge of the sternum.
Also note,at 400 yds,that 4 MOA post tip,taken to the edge for windage,would be right there at 400 yds for 10 mph.If I used that windage at 300,.the error would be+ 1.4 in.
For what I was doing,I had what I needed to hit heart/lung to 400 yds.
It worked at 300.Dead antelope.
I don't think Ineed to squeeze more ot of a 2.5 X scope on game.
If your scope is a typical variable,it would be real hard to work with,but for a fixed power,The trick is to match the hashmarks to your trajectory.You might need a 300 or 500 yd zero for the center cross hair.
I do not prefer busy reticles after trying a couple,(Rapid 800 and the Springfield Armory)too fine,takes too much concentration,and they disappear in poor light.
