High BC maintains velocity well. Energy at 500 yds: ~1,580 ft-lbs. Still adequate for big game.
Ballistic coefficient measures a bullet's ability to overcome air resistance. Higher BC means the bullet retains velocity better at distance, resulting in less drop and wind drift. Long, streamlined bullets have higher BCs than short, blunt ones.
| Caliber | Typical BC | Drop at 300 yds |
|---|---|---|
| .223 (55gr) | 0.243 | -12.5" |
| .308 (168gr) | 0.462 | -8.3" |
| 6.5CM (140gr) | 0.530 | -6.8" |
| .300WM (180gr) | 0.507 | -6.2" |
Bullet drop depends on muzzle velocity, ballistic coefficient, distance, and zero range. Gravity pulls the bullet down at 32.2 ft/s² regardless of velocity. Faster bullets reach the target sooner, experiencing less gravity drop. The calculator uses sight-line geometry relative to your zero range.
MOA (Minute of Angle) is an angular measurement used for scope turrets. 1 MOA equals approximately 1.047 inches at 100 yards. If your bullet drops 6 inches at 300 yards, you need about 2 MOA of adjustment (6 / 3.14).
This calculator provides good estimates for standard conditions. Real-world factors like wind, altitude, barrel length, exact BC, and ammunition lot variation cause differences. For precision shooting, use actual range data to verify and refine your drop chart.
