[QUOTE="TOM H, post: 1284569, member: 306"] I shoot the 180gr Spitzer and this may explain little on BC and this is from Sierra. There are at least three ways to describe the BC. First, it is widely recognized as a figure of merit for a bullet’s ballistic efficiency. That is, if a bullet has a high BC, then it will retain its velocity better as it flies downrange from the muzzle, will resist the wind better, and will “shoot flatter.” But this description is qualitative, rather than quantitative. For example, if we compare two bullets and one has a BC 25% higher than the other, how much is the improvement in bullet ballistic performance? This question can be answered only by calculating the trajectories for the two bullets and then comparing velocity, wind deflection, and drop or bullet path height versus range from the muzzle. I've never shot the 180gr PPT to compare but other calibers, I've always used SP partition. [/QUOTE]
