Angle Detection. 040 at 900 fps, since BC is proportional to SD. By sticking with this 120-year-old non-aerodynamic standard, bullet companies ensure their BCs will be as large as possible. Note that the distance can be in feet, yards, or meters by clicking on the desired unit of. 3 How The Ballistic Coefficient is Measured by Firing Tests Figure 4. Well, it is pretty much the same principle as number 7, but we need other variables to calculate this type of ballistic coefficient, such as mass, drag coefficient, and the cross-sectional area, instead of density and body length which are used in the 7th equation of our list. Muzzle Velocity. Cd = Fd / 1/2*p*V^2*A. I take the data from my LabRadar and run it through an online calculator and I get fairly consistent results. It is velocity, not kinetic energy, which is the quantity of greatest interest in the terminal ballistics of small arms. Velocity in feet per second. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. In this paper, the analytical solution of aerocapture based on the piecewise variable ballistic coefficient is studied around the exploration. BC is inversely proportional to the negative acceleration of the ballistic object. We are working on a massive list, but this list won't be ready for a few weeks or months. This will open the consecutive entry fields where the beginning velocity of the range, the distance of the range and the final velocity of that range may be entered. Trajectory is inches from line of sight. G1 Ballistic Coefficient Must be between 0. Ballistic Coefficient (lbf/in2). If only one BC value is given by the manufacturer, it is typically based on the G1 drag model. 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 expressed as a number. 0] [?] Far Velocity (500. Some bullet manufacturers provide this and it provides a more accurate solution. I zeroed the load at 200 yards and entered all the data into my ballistic calculator and went out to shoot steel and verify drops. The initial velocity (V 0), and then, at a certain point on the trajectory at the distance x from the muzzle, the V x velocity. Previous Page. A pellet of the same caliber that weighed half as much (SD = 0. Divide by 32 for standard. Draw weight in pounds. Although it is possible to design bullets with very high ballistic coefficients, this can be both beneficial and detrimental to bullet performance in terminal ballistics.

This built in ballistic coefficient calculator is to be used as a last resort. A bullet's ballistic coefficient then relates the drag on any bullet to that of the standard bullet. 356 and a muzzle velocity of 2960 ft/sec. different hop up "strengths" will change the entire equation therefor and because of this you will need to make multiple graphs for the different "strengths" as each. The maximum range of a handgun is determined by the muzzle velocity, ballistic coefficient, air temperature, amount of gun powder, angle shot and form factor. Is the drag coefficient still accurate to the graph at Re=10,000? How large of a difference is there between the actual value and the value produced by SolidWorks?. A Ballistic Coefficient calculator that can calculate Ballistic Coefficient valves using the POI change (∆POI), Velocity Change (∆V) or Elapsed Time (∆T) methods. Trajectory is inches from line of sight. Zero Distance in yards up to 40. Since a knowledge of the velocity and projectile construction is essential to evaluating the character of the kinetic energy and its wounding potential, simply relying on a quantity of energy can be quite misleading. Calculate Ballistic Coefficient From Velocity. The bullet is actually tracked through the air in real time measuring the velocity and distance. The ballistic coefficient for one hundred metres is calculated using the following. To measure V 0 directly is difficult; therefore V 5 and V 100 were measured, from which V 0 was subsequently extrapolated. maker name (if red, click for full ham review) weight head dia. The sectional density is the weight of the projectile in pounds divided by the square of the diameter ( SD=W/d2) and is an important number when considering penetration. BC is a function of mass, diameter, and. But it can also used for rifles or other bullets.
