A crystal or crystalline solid is a solid material whose constituents, such as atoms, molecules or ions, are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.nhedral crystals do not, usually because the crystal is one grain in a polycrystalline solid. The flat faces (also called facets) of a euhedral crystal are oriented in a specific way relative to the underlying atomic arrangement of the crystal: They are planes of relatively low Miller index.
Answer Wiki. Actually, in modern warfare, tracers are not used as they were during previous wars. They were originally used to allow gunners to track where their small caliber bullets were actually going. However since their ballistics were quite different than the standard rounds, they only gave a rough estimate for targeting.
Also the facft that you are shooting a rifled slug through a rifled barrel would cause the bullet to become extremely unstable and inaccurate. Rifle barrel sare meant for sabot slugs (slugs with a plastic wad surrounding the outside).es, you can shoot rifled slugs out of a smooth-bore barrel with any choke. Pattern with different manufacturer's slugs, and at different distances to see which works best. â¦ Different guns like different ammo so see what yours likes. If it is a smooth-bore, do not use sabots. 7 people found this useful.
