[QUOTE="Hobbes, post: 1285932, member: 3371"] Given the same propellant charge, a lighter bullet will generate less chamber pressure than a heavier bullet. Study the reloading manuals for a given caliber-propellant but different bullet weights. You will notice that as the bullet weight increases, the propellant charge is decreased. Modern propellants are progressive; they burn faster when they are under more pressure. So, with a heavier bullet to push they are under more pressure and burn progressively faster. Therefore, the charge must be reduced for the heavier bullet to maintain the same pressure. [/QUOTE]
