This doesn’t make sense, say 10 grains of the same powder produces the same energy. If the back of the bullet has the same surface area for the force to be applied to, then the lighter bullet (say 100 grains) should move faster than a heavier bullet (say 300 grains) using the same force unless some other factor is involved. OK, I over exaggerated the weight difference to make a point. Bigger cars use more gas because they are heavier, the same thing, no???
