Show sample as: 72-frame QuickTime VR or 360-frame QuickTime movie loop.    My periodic table poster is now available! Bullet blank. This small (1/4" diameter) rod is from a munitions factory and was meant to be machined into a bullet shape. Tungsten is used for very fancy bullets because it's hard and dense, allowing it to carry a lot of energy to the target.
