Jul 11, 2012 · This is a .223 ballistics chart (external) generated using our ballistic trajectory calculator. Based off a standard 55gr bullet leaving the barrel at 3,215fps and follows the bullet trajectry all the way to 1000 yards in steps of 50 yard increments. The charting shows the range, drop (based off a 1.5" scope mount), current velocity, energy

### All About Ballistic Coefficient Airgun Depot

Aug 29, 2018 · What is ballistic coefficient (BC)? Without getting into the math, BC is basically a measure of a projectiles ability to maintain velocity as it flies through the air. It is calculated based on the sectional density (weight of the projectile in relation to its diameter) and form factor or shape of the projectile and is eed as a number Ballistic Coefficient & Bullet Math :Long-Range Shooting Jul 16, 2018 · Ballistic coefficient (BC) is a mathematical representation of how efficiently a bullet flies through the air. A bullet with a high ballistic coefficient is slippery and less subject to drag

### Ballistic Coefficient - Hornady Manufacturing, Inc

Ballistic Coefficient (BC) values can, and usually do change in value with changes in velocity. Most bullets exhibit a lowering BC as velocity slows. The extent of how much a BC will change depends on each unique bullet shape. When comparing BCs of different bullets, it is important to use an apples-to-apples approach. Ballistic Coefficient Calculator GunDataThe Ballistic Coefficient is the ability of a bullet to overcome or beat air resistance as it is flying through time and space, and this is basically the exact opposite of the negative acceleration.

### Ballistic coefficient - Simple English Wikipedia, the free

In ballistics, the ballistic coefficient (BC) of a bullet is a measure of its ability to overcome air resistance in flight.A high BC means the object will slow down less. It will have more of its speed left when it reaches the target. BC depends on mass, diameter, and drag coefficient.Ballistic coefficient has units of lb/in² or kg/m².

### Basic Bullet Ballistics, Definitions, & Concepts To Understand

Dec 02, 2017 · Basic bullet ballistics is the understanding of everything that will happen to a bullet once it leaves the barrel of your firearm. Even if you never do any long-range shooting, and just go plinking once a year, you still need to understand bullet ballistics. The basic understanding of bullet ballistics will help you know how to sight in your gun. Bullets vs. Wind - RifleShooterJan 04, 2011 · There are two key elements to understanding a bullet's susceptibility to wind drift. The first is its ballistic coefficient (BC), which combines the air resistance of the bullet shape (the drag coefficient) with its sectional density (the ratio of its frontal surface area to bullet mass), and is eed by a figure providing the ratio of its ballistic efficiency compared to a standard

### The Ballistic Coefficient of Rifle Bullets - CHUCKHAWKS.COM

By Chuck Hawks. Ballistic Coefficient (BC) is basically a measure of how streamlined a bullet is; that is, how well it cuts through the air. Mathematically, it is the ratio of a bullet's sectional density to its coefficient of form. Ballistic Coefficient is essentially a measure of air drag. The higher the number the less drag, and the more efficiently the bullet cuts through the air. Understanding Ballistics and Ballistic Coefficiency Ballistic coefficients are only one factor in bullet selection for different kinds of shooting. A ballistic coefficient can change with reference to (1) altitude, (2) temperature, (3) atmospheric pressure, and (4) relative humidity. Ballistic coefficients are measures of a bullets relative efficiency.

### Understanding Long Range Bullets Part 1:The Nature of Scale

even the almighty ballistic coefficient is not beyond comprehension for those who understand the nature of scale. I give you, the equation for ballistic coefficient1:i d2 m BC = m = mass of the bullet in pounds (weight in grains divided by 7000) d = diameter of the bullet in inches i is the form factor close to actual weights. What You Need to Know About Ballistic Shooting Sports May 22, 2019 · When entering a drag model into your ballistic computer, always be sure to match the ballistic coefficient with the drag model. For example, the Hornady 6.5mm 140-grain ELD Match bullet has a ballistic coefficient of .646 using the G1 drag model. The G7 model uses a ballistic coefficient of .351 for the same bullet.

### What is the difference between G1 and G7 Ballistic

Oct 08, 2014 · G1 and G7 are different models of drag functions that measure ballistic coefficient. Ballistic Coefficient or B.C. is a measurement (or prediction in a lot of cases) of how fast a bullet slows down in a given distance with a given velocity. G1 and G7 both measure the aerodynamic qualities of a bullet but use different models to do so. Why Hunters Prefer High Ballistic Coefficient BulletsFeb 25, 2015 · If you're a .280 Rem. shooter you know there's not exactly a ton of choices in factory ammo, so most of us reload it. And that was a good thing in this case because it allowed me to try two relatively new bullets designed specifically with ballistic coefficient in mind:the Nosler 150-grain AccuBond Long Range (ABLR) and the Barnes 145-grain LRX.. The Nosler's BC is a whopping .611

### Ballistic Coefficient:Everything You Ever Wanted to Know

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, its the ratio of the bullets sectional density to its coefficient of form. In short, a high ballistic coefficient is indicative of a
