[QUOTE="CatShooter, post: 130694, member: 7"] [ QUOTE ] In alot of cases (all cases), differant bullets will have a differant BC for a given powder charge, load density, barrel length, twist rate, velocity, air density, and I am sure a few other things we havent discovered yet. [/ QUOTE ] I'm sorry... but the BC of a bullet has NOTHING to do with powder, load density, twist, primers, or anything else internal to the rifle... ... BC starts when the bullet hits the air, AFTER it leaves the barrel, and it only relates to the bullet's ability to pass through the air. Himidity, air density and temperature do NOT affect BC. BC is a mathamatical quality of the shape of the bullet... nothing more. . [/QUOTE]
