G7 ballistic coefficient
What cartridge has the highest known ballistic coefficient?
What cartridge has the highest known ballistic coefficient? Well the direct answer to the question, (as no further info was requested, and assuming factory loads) is the Hornady A-Max 750gr .50 Browning Machine Gun cartridge developed for target/match shooters and has a ballistic coefficient of 1.05 on G1 drag model.
What is the difference between G1 BC and G7 BC?
What is the difference between G1 BC and G7 BC? The difference between G1 BC and G7 BC is that the G7 BC is more representative of modern long-range bullets. The G1 BC has traditionally been the ‘standard projectile’ used to define BCs for the entire sporting arms industry. The problem herein lies that Berger Bullets aren’t standard projectiles.
What is a good ballistic coefficient?
What is a good ballistic coefficient? Admin Mar 12, 2022 General trends. Sporting bullets have BC's in the range 0.12 to slightly over 1.00, with high being the most aerodynamic, and low being the least. Very-low-drag bullets with BCs ≥ 1.10 can be designed and produced on special lathes using mono-metal rods.
What is a high ballistic coefficient?
The definition according to Wikipedia is, “the ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight.” Put another way, it’s the ratio of the bullet’s sectional density to its coefficient of form. In short, a high ballistic coefficient is indicative of a rounds ability to resist drag.

G1 BC: The Ballistic Coefficient referenced to the G1 standard. Use this BC for flat base bullets. G7 BC: The Ballistic Coefficient referenced to the G7 standard. Use this BC for boat tail bullets. G7 Form Factor: The drag of the bullet compared to the G7 standard.

Modeling the Projectile: G1 vs. G7 Standards A bullet's Ballistic Coefficient (BC) is a measure of how well a bullet retains velocity. There's lots of smoke and mirrors surrounding the actual meaning of the BC, but it's actually quite simple to understand. Mathematically, the BC is the Sectional Density (SD) divided by a form factor. SD is a

One obvious difference between G1 BCs and G7 BCs is that the numeric value of the G7 BC is lower than the numeric value of the G1 BC. For example, if a bullet has a G1 BC of .550, the G7 BC will be close to .282

energy. This project compares ballistic coefficients advertised by four well-known bullet companies (Hornady, Nosler, Sierra, and Barnes) with those measured by an independent source (Bryan Litz). G1 and G7 ballistic coefficients were determined using calculations at the JBM Ballistics web site. Many published ballistic coefficients are ...

The G7 Ballistic coefficient does a better job of predicting the trajectory of modern long ogive, boat tail bullets to longer ranges than the G1 standard, however, it is still not modeling the exact Cd value or shape and will result in errors.
