Wrong way to think about it. Lighter bullets develop less pressure for the same amount of powder, so you can use more.. . . I was surprised to see lighter bullets needed more powder than heaver bullets.

After some testing, the 158 grain on the left with 3.3 grains of Win 231 is a nice experience. Those bullets are loaded, so now I have some 125 grain coated bullets as shown on right. Should I start a little lighter than 3.3 grains?
It’s a question of case volume and fill quantity. If a case is only 20% full it may have trouble igniting.
To add you may want to test with the powder forward (away from the primer) and near to see how large the spread you will have. Don't be surprised if you see a 200 fps difference. The main thing is make sure you have the powder charge high enough for the bullet to clear the barrel and hit your target. On large cases it can be significant.
