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.
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. Barrel Twist The twist length of the barrel. Twist DirectionThe world renowned JBM Ballistics computer is powering all of Ballistic's computations. JBM is used by world-class shooters everywhere to deliver some of the most precise calculations. You'll even be able to take JBM's extremely accurate calculations with you, even into areas with no cellular coverage.This means that it is the ratio of the drag function and ballistic coefficient that model the drag of the bullet. For different drag functions, the Cs will be different, but with properly chosen Cs and drag functions, the same trajectory will be calculated because the drag force is the same.I was under the impression that in order to calculate a bullet's ballistic coefficient, one had three choices: a) Muzzle velocity compared to and calculated against some "meaningful" downrange velocity b) "Point of Impact" Method c) Doppler Radar (a variation I assume of a), above) Now, it...

This bullet has a length of 1.248 inches and would be over stabilized in my 6.5 Creedmoor according to Bison Ballistics below at a speed of 2400 fps. However, the Miller Stability formula on the other hand in JBM Ballistics below says the Lapua round nose 155 is stable enough and shades it in green.

Calculate recoil from muzzle velocity and bullet, powder and rifle weight.The G7 Ballistic coefficient does a better job of predicting the trajectory of modern long ogive, boat tail bullets to longer ranges than the G1 standard, however, it is still not modeling the exact Cd value or shape and will result in errors. Utilizing the popular and well-designed JBM ballistics code, Table 1.The velocity at which the ballistic coefficient entered above is defined. If you only have one BC and no velocity information, use the average of the muzzle velocity and terminal velocity so that you get a new ballistic coefficient representative of the velocity range you are using.

For now, we will set aside Coriolis, spin drift, and uphill/downhill calculations. For any bullet, the drag force must be the same no matter what drag function is chosen since the drag force is physical and depends on the shape of the bullet. This means that the following equation must be true. G (M)/C = G (M)/C. where j is a different drag function than i.
