What PPU ammunition might that be? Without knowing that we can't help you.

We need -

1. Calibre and bullet weight.

2. Muzzle velocity.

3. BC of bullet if possible.

Don't forget the scope height too

do you have the opportunity to shoot at 500? is there a marker? if so the easiest way is to go to the range put on an average drop for 500 and take a shot, the marker will show where the shot hits (if you are correct in your 300 zero then it should hit on target frame...somewhere ) adjust for fall of shot and keep note of the adjustments, a ballistic chart is only going to get you into the vicinity unless you have all the variables tied down.

try 57" as a starter (based on 168grn PPU BTHP at 2700fps)

your original drop of 12.5" at 300 from a 150 zero looks all wrong are you sure of that? (I am assuming that the drop is the adjustment from 150 to 300 )
or play with this

Your figures do not seem right.

Zeroed at 100 yards I would expect a drop of only about 6 inches at 300 yards.
