The JBM IDPA classifier application is a simple application for IDPA classifier practice. It allows the user to enter classifier times and points down and calculates the current classification. It includes the abbreviated classifer, the standard classifier and the pistol caliber carbine classifier.Ballistics calculations and formulas for small arms. Drag/Twist. Calculate drag and stability from bullet dimensions, weight, specific gravity and barrel twist.I built it from gathering some information together and running it through JBM Ballistics. So what data do I need? First, you must know the bullet you're firing. In my case, that's a Lapua Center-X 40gr 22LR cartridge. Lapua lists the ballistic coefficient (BC) as a .172 G1. Second, you have to know your velocity.
Many modern ballistics programs, including the free online JBM Ballistics Program, are able to use BCs referenced to G7 standards. When available, these BCs are more appropriate for long range bullets, according to Bryan. [Editor's NOTE: BCs are normally reported simply as an 0.XXX number. The lb/in² tag applies to all BCs, but is commonly ...
The BASIC programs were given to me by the late Robert L. McCoy and posted here with his knowledge. He worked at the US Army's Ballistics Research Lab for many years, where he wrote these programs as part of his work. I have made some changes to these programs (with Bob's knowledge) only as necessary to fix bugs.

Just make sure you measure your scope height from the center of the scope down to the center of your bold for the closes number you can. then shoot!The drag function to use to calculate the ballistic coefficients. Most commercial bullets use the G1, but for some long range bullets, the G7 or G8 is typically a better choice. Some military bullets fit the G5 and G6 functions better than the G1.

The BC, or ballistic coefficient is defined as: BC = w / [i d 2] here the diameter is specified in inches and the weight in pounds and the form factor is found using: i = CD / CD G. The sectional density is defined as: SD = w / d 2. making the ballistic coefficient BC = SD / iThe BASIC programs were given to me by the late Robert L. McCoy and posted here with his knowledge.

Ballistic coefficient facts. 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.
