Sierra Bullets Ballistic Coefficient Charts

If you are just getting started with precision shooting, you have likely heard the term “Ballistic Coefficient” thrown around by experienced shooters. It might sound like intimidating physics, but it is actually a straightforward concept: it is simply a measurement of how well a bullet “cuts” through the air. A higher number means the bullet is more aerodynamic, retains its speed longer, and is less affected by wind. Sierra Bullets is a gold-standard name in the industry, and their ballistic coefficient (BC) charts are the essential tools you need to predict exactly where your shot will land before you even pull the trigger.

Understanding the Statistics

The table provided above is a comprehensive reference for many of the most common Sierra bullets. For a newcomer, these numbers might seem like just another set of technical specs, but they are the keys to long-range accuracy.

Decoding the Metrics

Bullet Type: This identifies the specific family of the projectile. Each family is engineered for a different purpose, ranging from explosive performance on varmints to high-precision target engagement.
Caliber: This is the diameter of the bullet in inches. It is crucial to match this exactly to your rifle’s barrel specifications.
Weight (gr): Measured in grains. Heavier bullets typically have a higher BC and are less susceptible to wind, but they require a faster barrel twist rate to stabilize during flight.
Style:
HP/HPBT: Hollow Point/Hollow Point Boat Tail. These are usually designed for match-grade accuracy.
TMK: Tipped MatchKing. These incorporate a polymer tip to improve aerodynamic efficiency, providing a higher BC.
SBT: Spitzer Boat Tail. A classic design that balances range and terminal performance.
SPT/FN: Soft Point or Flat Nose. These are typically used for hunting, where terminal performance and mushrooming are prioritized over extreme long-range ballistics.
G1 BC (Avg): This is the numerical representation of how well the bullet slices through the air. A higher number is almost always better for long-range performance, as it means the bullet loses velocity more slowly and drifts less in crosswinds.

Why This Matters

When you are just starting out, using these charts allows you to input the correct data into a ballistic calculator. By knowing the weight and the G1 BC of your chosen bullet, you can predict exactly how much your bullet will drop at 300, 500, or 1,000 yards. Always ensure you are using the specific BC for the exact bullet you have on your bench, as even a small difference in bullet profile can lead to a missed target at long distances.
