Two weeks after its introduction, the Hybrid Target bullet began winning matches, and it continues to do so. Don't be confused the next time you hear "ballistic coefficient" tossed around by long-range shooters. First Focal Plane vs. Second Focal Plane Scopes Explained: Which is Best? Ballistic Coefficient (BC) values at Mach 2.25 (2512 fps @ ICAO Standard Atmosphere) should be used when comparing to other published BC values within the industry. Scott Rupp gets a chance to talk to Aaron Oelger about a few new products from Hodgdon and why reloading store shelves are empty. Get proficient on YOUR time. When comparing BCs of different bullets, it is important to use an apples-to-apples approach.

Which explains why .22 bullets drop so much at long range and are so subject to wind drift, compared to larger caliber bullets with superior sectional densities (and hence, BC's). If a Mach number is unavailable, velocity can be used if the BCs are corrected to Standard Atmosphere which is fairly typical practice within the industry. ELD-X stands for Extreme Low Drag eXpanding bullet. Thats where it started, and since then its gone from simple experiments all the way to engineers and scientists at places like Aberdeen Proving Ground working to improve ballistic calculations. BC is what determines trajectory and wind drift, other factors (velocity among them) being equal. Its just the love that goes into solving the problem. Ballistic Coefficient (B.C.) Comparing Ballistic Coefficients (BCs) | Berger Bullets Heck, few whitetails, antelope, mule deer and even average black bears measure much more than 12 inches broadside through the vitals. Even their ammo is great. Ballistic coefficient is typically measured with a 3 digit expression. The following at the most standardized: The G1 is the oldest and still the most commonly used. Newly Published base of comparison. Hornady A-Tip. Its great for accurate target shooting. Unfortunately its not as simple as just comparing the single numbers.
