[QUOTE="eddybo, post: 357756, member: 7194"] I really have no business posting in this discussion as it is way over my head. I really do not care how the number is derived, what it represents, or any significance of BC other than this one thing........when I plug that sucker into a ballistics program, are my drops and windage corrections correct. Whether that number is correct or contrived, if it works to give me information that allows me to hit stuff at whatever range, then the BC is correct to me. I gave up a long time ago trying to wrap my little brain around the engineering aspects of long range shooting and external ballistics. But, I have some questions, something that came to mind recently during all of this debate on BC, is what happens to a bullet when fired? What dimensions of said bullet change? Doesn't a bullet obiturate (can't spell it or even know exactly what it means). What effect could this have on BC? Could this "swelling" of the bullet cause a change in BC? Couldn't this "swelling", since each barrel is different cause BC to vary from barrel to barrel? [/QUOTE]
