I'm just trying to get some understanding of load theory. From my understanding, when going to heavier bullets in the same caliber, the factor preventing obtaining the same velocity is that the volume in the case will decreases because the bullet is presumably longer, so you can't use the same amount of powder or you will exceed the pressure limit whatever it might be.
But let's say we have two bullets, both copper plated with the same dimensions, one with a lead core weighing 180 gr total, the other one with lead+ core, weighing 200 gr. That's a 11% weight increase.
How would that compare to an 11% case volume decrease for two bullets with the same weight and obviously different dimensions?
