The BC is proportional to the product of the sectional density and the shape factor.
The sectional density is the weight of the bullet divided by the square of the diameter, so is proportional to the weight if the she remains fixed.
So, when the shape is fixed, and one changes only the weight, then the BC is proportional to the weight.
The advantage to lightening a sleek bullet is increased MV while retaining a presumably good shape factor, so there may be a gain in performance depending on what one is trying to accomplish.
