Bored at home, I was cruising through CTD's .357 mag for sale. Not going to buy any - really expensive right now; but I came across two measurements that have me wondering: sectional density and bullet ballistic coefficient. For reference, S&B .357 advertises a sectional density of 0.177 somethings (no units included) and Magtech sports a bullet ballistic coefficient of 0.149. What are these? I suppose I could Google but I really want to know is: Why should I care? Is 0.149 better than 0.170 (which is the ballistic coefficient of Winchester Super X, 158 grain) if the two bullets are the same price?
Pointless questions, I know. But I'm really bored.
Does anyone use these figures?
