How Is Your Ballistic Coefficient IQ?
Rifle-bullet ballistic coefficients are often misunderstood. And ballistic coefficient (BC) in relation to rifle bullets is the new hotness as more hunters develop long-range aspirations. BC relates to sectional density, a projectile’s length in relation to diameter, and how this dictates how efficiently bullets slip through the atmosphere. Atmospheric resistance affects bullet drop and wind drift most noticeably as ranges move beyond average. For most deer hunters, who rarely shoot beyond 200 yards, BC is a nonfactor, except in extreme cases, such as launching round-nose pills from something like an antiquated .30-30 Winchester or .35 Remington. Yet though BC is a hot topic, many old wives' tales persist. Let’s explore some of these myths as they relate to BC.
