[QUOTE="MAX, post: 28284, member: 184"] A discussion in this site awhile back pitted disciples of different ballistic persuasion, one using homogeneous copper alloy bullets, the other discussing bullets with tungsten cores, the idea as I understood it being a denser core having superior ballistic properties. So, denser than what? Tungsten(atomic wt. approx. 183) is denser than copper(atomic wt. 63), but not as dense as lead(Atomic wt. approx 207). The only material I see denser than lead that may be useful is bismuth(atomic wt. almost 209) due to availability and characteristics. I am not trying to start a riot with this, but if I missed something, please clue me in. [img]images/icons/confused.gif[/img] The formula for BC involves form, diameter, and weight; the limitation on long forms being largely the required twist to stabilize it. Wherein lies the ballistic advantage of lighter core materials than lead? BC is proportional to SD for a given form after all. [/QUOTE]
