Threads. 472,824.A selection of bullets with different shapes, and hence, different ballistic coefficients. In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.

At the muzzle, the .30-06 Springfield has right at 200 more ft.lbs of energy than the .308 Win rounds. Which was a little higher than what we saw from the small set of rounds that we graphed. As the rounds move out further, the difference between the two cartridges diminishes to around 75 to 100ft.lbs of energy.The JBM Ballistics engine utilizes Litz-derived Ballistic Coefficient (BC) values, based on field testing by Bryan Litz, a champion shooter, aerospace engineer, ballistician, and author of the highly regarded Applied Ballistics for Long Range Shooting. The BC is a measure of the capability of a projectile to overcome air resistance in flight.Range Officer. Staff member. Nov 4, 2004. 24,336. 6,640. Noslers app hasn't been around for a while.

Compare these ballistic calculator outputs, particularly the "Maximum PBR" range in the first column. The first is with a 20″ barrel firing M193 at 3300 FPS, the second is a 16″ barrel at 3100 FPS, and the third is a 12.5″ barrel at 2900 FPS. These represent my three favorite barrel lengths for an AR-15.Gentlemen - I need your help. This morning, I shot in a local event 3 relays of 20 rounds for score + 2 sighters @ 600 yards.

If checked, the windage is changed to make the bullet cross the line of sight at the zero range -- zero windage at the zero range. Wind Angle. The angle of the wind relative to downrange (0 degrees), 90 degrees is to the shooter's right, 180 is a head wind, and 270 degrees is to the shooter's left. Wind Speed 1, 2 or 3.Further more, some manufacturers (Lapua) are skipping the ballistic coefficient and drag function all together and releasing tables of drag coefficient versus mach number. Drag Force The relationship between different drag functions and their ballistic coefficients can be shown using the following equations.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 … ….
