Do not agree with
“It should take slightly more powder to push a heavier bullet,”
That is true if you want to push the heaver bullet at the same velocity, BUT that equals more pressure. In fact the heaver bullet with the same powder charge will also make a heaver pressure. That’s why a heavier bullet takes less powder for a proper load.
I am not at home right now or I would look at all my books for a load that might work for you but use the lighter bullet load and stay 10% under max. Use the min to max load and subtract 10%. Your also going to find that the max load will not give you the best accuracy but that some where near the middle load will. Don’t worry, your pushing a big bullet fast enough to rune any bad guys day.
