The classical equation to calculate gyroscopic stability is as follows. ( Sg S g) is the gyroscopic stability factor, and must be above 1.0 if the bullet is to remain stable. Sg = 8π ρairt2d5CMα A2 B S g = 8 π ρ a i r t 2 d 5 C M α A 2 B. The variables are as follows: The gyroscopic stability factor. A bullet is stable if Sg S g is over 1.0.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 Library10 May 2010 -- Add JLK bullets. 3 May 2010 -- Complete update of website for announcement of BallistiComp. 15 March 2010 -- Modified point mass calculations to include changes in atmosphere when shooting uphill and downhill. 11 January 2010 -- Fixed humidity output units and updated bullet library. 16 November 2009 -- Fixed a drop units …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).

Are you talking a generic drop chart for A171 or FGMM? 168SMK doesnt give you enough information velocity can play a huge part in the ballistic drop. If you are only pushing it at 2500 fps out of your gun your drop chart will look completely diffrent then if you are pushing it at 2800 fps.JBM Ballistics is a powerful ballistics calculation tool, but it does have some limitations: first, it doesn’t calculate Coriolis effect; second, it doesn’t have separate columns for spin drift (which is calculated with wind drift) and uphill/downhill. For now, we will set aside Coriolis, spin drift, and uphill/downhill calculations.

If you look at the bullet drop for two bullets, one with a BC of 0.5 and the other with a BC of 0.55, you'll find that the bullet drops at 300 yards with a muzzle velocity of 3000 f/s and a 100 yard zero, are -10.9" and -10.7" respectively. So if you can shoot groups less than 0.2" at 300 yards, have at it.

These statistics [calculated Wednesday, March 20, 2024 at 16:25 MDT] are based on the last 31 days of bullets chosen from the bullet library.

A very nice book on common and uncommon drag functions. Book includes printout of computer code to model drag functions and choose drag function for a bullet. A must have for anybody interested in exterior ballistics.A drag function (or G function) provides the forces on a standard bullet for which the drag function was derived. A bullet's ballistic coefficient then relates the drag on any bullet to that of the standard bullet. The velocity of the bullet at the beginning of the measured distance. The barometric pressure.Used for sectional density and form factor calculation. Drag Function. The drag function for the enter ballistic coefficient. Velocity. 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 ...Suggestion: Zero in your outfit at 50 yds, then, on a clean target, shoot a 5-shot group at the same distance. Circle this group with a pen or whatever and write "50" next to it. Next, take the same target and put it up at 100 yds, and shoot another 5-shot group. Circle this group, and label it also.

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 …
