Re: Rem.Ballictics showing up wrong??
Remember, there are three kinds of lies: Big lies, Little lies, & Statistics. SD is the ratio of bullet's weight in pounds divided by its diameter in inches. A higher SD "usually" indicates a better chance of penetration, since more weight vs diameter means a longer bullet. BC is the ratio of the sectional density of a bullet to its coefficient form. BC represents the projectile's ability to overcome the resistance of the air in flight.
Two bullets, same diameter and weight, one round nose & one spitzer; both have the same SD. Obviously, the spitzer will have the higher BC. What looks funny in ballistic charts is comparing apples & oranges. If bullets of different BC are shown as in your example, you MUST compare the same velocities to compare apples to apples. Lighter bullets go faster, heavier bullets go slower. Looking at ballistic charts you usually have different velocities compared head to head. The "lies" of statistics. Go to a ballistic program on your computer and compare two BC at the Same velocity and you will see a difference. Comparing two bullets of the same weight from two different manufacturers will often open your eyes unless both BC are the same. The Winchester Failsafe is a good bullet, but it has a low BC. At long range, trajectory and energy (factor of weight & remaining velocity)really suffers for the Failsafe.
