[QUOTE="Greasegun, post: 1838676, member: 112196"] Mass=volume x density. Lead has a significantly higher density than copper. Thus leading to higher B.C. with the same shape. [URL='https://www.vcalc.com/equation/?uuid=74c38ad1-3f7e-11e3-83ad-bc764e049c3d']B.C. Calculation[/URL] is affected by the mass of the projectile. See above link but here is the breakdown [B]"The Math / Science[/B] Ballistics is the science of mechanics behind projectile flight, behavior of objects during un-powered trajectories, and the effects of projectiles.

Which one will fly further? This is why given the same shape and size, copper bullets will be lighter than lead core bullets, therefore ballistically inferior. [/QUOTE]
