Higher or lower ballistic coefficient

Web12 de abr. de 2024 · Like the 6.5 Creedmoor, while capable of taking down larger game animals with good shot placement, it is not necessarily the best choice for hunting elk or moose. Because most 6.5mm projectiles have a high ballistic coefficient and a lower trajectory, this cartridge is also a good choice for competitive long-range shooting. … Web19 de out. de 2024 · Generally, the higher the altitude, the less the bullet will drop. For example, I shoot at a couple ranges here in the Pacific Northwest. Both are at 1000′ AMSL (Above Mean Sea Level) or less. I’ll need about 29-30 MOA to get from 100 yards to 1000 yards with a Berger 155gr VLD at 2960 fps.

Is a higher ballistic coefficient better or worse? – Heimduo

WebThe key is understanding that CD is a coefficient. It doesn’t represent the force of aerodynamic drag in pounds or any other units. The coefficient of drag is just a number that says how much drag a certain shape will have at any given speed. More streamlined shapes have lower drag coefficients, and blunter shapes have higher drag coefficients. WebCommon sense suggests that a bullet might perform better in higher temperatures (less dense air), at lower barometric pressures (less air pressure), and at higher altitudes … cryptography rutgers reddit https://corbettconnections.com

WebTHE BALLISTIC COEFFICIENT . William T. McDonald . Ted C. Almgren . December, 2008 . The term “ballistic coefficient” is familiar to most shooters today. They know that the ballistic coefficient of a bullet is a measure of how well it retains velocity as it travels downrange and how well it “bucks” the wind. However, few shooters really know Web11 de abr. de 2024 · “@caviterginsoy @SpaceDevClub @Neo_EimajOzear Yep. Basically 1/8th power. Convective heating, which dominates, is proportional to square root of air density, which is proportional to ballistic coefficient (given comparable trajectory).

WebIn brief, the ballistic coefficient is a mathematical representation of how streamlined a bullet is, i.e., projectile's ability to resist air drag. As a numeric designation, the ballistic coefficient (BC) is usually described as a number between one and zero. Common FAQ Is a higher ballistic coefficient better than lower? WebA high BC bullet can maintain velocity better than a low BC bullet under the same conditions. All measures of ballistic performance including drop and wind deflection are …

WebEffectively, the bullet behaves as if it has a higher ballistic coefficient. Forum members Milanuk explain that the key factor is not altitude, but rather air pressure. Milanuk writes: “In basic terms, as your altitude increases, the density of the air the bullet must travel through decreases, thereby reducing the drag on the bullet. Web9 de fev. de 2005 · 2.
