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.
Size & 22LR Ballistics. The 22 LR is a tiny round at only 1" long. Its low power means it gets by with a very thin brass shell casing, a contributing factor to its nice price tag. Such a thin casing enables a rimfire primer, which is struck through the brass by the firing pin. Still, the 22 LR's muzzle velocity is nothing to scoff at.Watch this video to learn how to find wall studs behind a ceramic tile bathroom wall in your home from home improvement expert Danny Lipford.

You can also put the info in an Excel spreadsheet or MS Word table and print it out. Above is a sample of a data card. For each distance, the card includes drop in inches, drop in MOA, drop in Mils. The Sierra Reloading manual has a section on Exterior Ballistics which provides the differential equations of motion, as does "Exterior Ballistics" and "Mathematics for Exterior Ballistics". Calculation of a trajectory also requires calculation of atmospheric density as a function of temperature, pressure (sometimes humidity, if you want).Trying to produce a chart for .308 168 Sierra Matchking. Using BC of .462 and with G1 specified it shows I need to hold over 414 inches at 1000 yards. If I change nothing other than changing G1 to G7 it says I only need to hold over 295 inches. That's a pretty huge difference. Been trying to...
JBM Ballistics has partnered with RIANOV to provide integrated ballistics solutions, including the M06 passive ranging calculator, the SOLO calculator and the CSI.

This motion involves the velocity and rotations. It is represented by the following equation. KE = 1/2 M v 2 + 1/2 I w 2. NOTE: this assumes a single rotational axis and forward motion of the bullet. For multiple rotations and non-symmetric bodies, things get a little more complicated.
This book, among other things, includes software and experimentally measured ballistic coefficients for 175 bullets.

For the less eager, there are several approximate methods of calculating the required spin for a bullet. The simplest is the old Greenhill formula: T = 150 / L. where T is the twist in bullet calibers, and L is the length of the bullet in calibers. Unfortunately, it's not a very good method, but I include it here to show that longer bullets ...what has happened to JBM ballistics, I use to use this site alot for checking different loads and calibers.

The on-line ballistics page can correct for the distance to chronograph.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 ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Bullet Length The length of the bullet.Ballistic Coefficient The ballistic coefficient for the bullet being used. It is almost always obtained from the manufacturer, but can also be measured.
