Founded by Frank Galli in 2000, Sniper's Hide has been offering informational videos, podcasts, and other support to its users in one location. Forum Statistics.Kinetic energy is a function of the bullet mass and motion. 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.The distance from the point of the first velocity measurement to the point of the second measurement. This is the distance between the two chronographs. Drag function. 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 ...Changing Variables of Integration. From the discussion on CD and KD, we know that the acceleration of the bullet is. a = - k v + g. where. k = = p/p 0 G (m)/C. Rewrite the acceleration as a derivative. a = d u / dt = - k ( u - w) + g. Define a coordinate system where y is the range variable, x and z are perpendicular to the trajectory where x ...Using the velocity numbers from the 4DOF program (and yards instead of feet ), the JBM Ballistics program gives me a G7 of .362 for the first 100 yards and a G7 of .317 from 900 to 1000 yards. If I use the MV and 1000 yard velocity I get a G7 of .341, and MV - 700 yards give a G7 of .351 which is the published G7 from Hornady for the 6.5mm 147 ...

External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field ...

Ballistic Coefficients BCs and different drag functions? What is the best one to use? Cant Derivations of the equations used in corrections to the elevation and azimuth of a canted firarem. CD and KD Derivations of the equations used in the point mass trajectory calculations. It includes equations for CD, BC and KD. CrosswindA 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 …This is done by measuring the drag of the standard bullet. This standard bullet has a ballistic coefficient (BC) of 1.0. Other bullets of the same shape but different size have different ballistic coefficients. The drag function and BC are then used to calculate the drag coefficient and therefore the drag on a bullet of similar shape to the ...I use jbmballistics online and would like to take my portable with me to the range.

The Ballistic Edge is further enhanced by the data in the huge Ballistic Library, home to over 5,400 projectiles and factory loads. The Library is updated regularly to include new offerings. The Library and the JBM ballistics engine go to work the second a shooter begins to build his or her own Ballistic Bullet Profile. That Profile contains ...Since w x is constant, one can readily perform the integrals (assuming constant k) . u x = w x [ 1 - u y /u x0] . Integrate one more time with respect to t on the interval [0,t] x = ∫ u x dt [0,t] = w x [ t - R/u x0] . where R = ∫ u y dt [0,t] . and x is the deflection, u x0 is the muzzle velocity (initial velocity in the y direction), R is the range, t is the time of flight to that …k 4 = h F ( x n + h, y n + k 3 ) The equations of motion for a bullet in flight, are simultaneous coupled differential equations. Specifically three equations for acceleration, position and spin. These equations may have been transformed using the substitution: d u /dt = d u /dy dy/dt = d u /dy u y.Changing Variables of Integration. From the discussion on CD and KD, we know that the acceleration of the bullet is. a = - k v + g. where. k = = p/p 0 G (m)/C. Rewrite the acceleration as a derivative. a = d u / dt = - k ( u - w) + g. Define a coordinate system where y is the range variable, x and z are perpendicular to the trajectory where x ...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.

JBM ballistics is the best thing I have found and I do a LOT of long range shooting and I fancy myself pretty proficient at it. 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!Both Winchester and JBM ballistics have fairly comprehensive libraries with all of this information included with particular Winchester cartridges or bullets in the case of JBM Ballistics. The final piece of information you'll need is the height of the center line of your scope over the rifle bore. In most modern firearms this ranges from ...Since not everyone has a pressure measuring device, some ballistics calculators (like the popular JBM Ballistics) let you input corrected pressure and an altitude so that it can convert the corrected pressure to an absolute pressure. I don't recommend doing this. First, because a corrected pressure from an airport nearby will always be less ...Sparks, Nevada. Feb 8, 2010. #6. did this really quikly.

I think you will find that Applied Ballistics is probably the most well regarded. My personal opinion is that Strelok would be next over the apps you mentioned. Be careful comparing two dissimilar things that appear to be similar. For example I was messing with my Kestrel elite and comparing some data to Strelok+ at 100 yards.

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.

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. This means that it is the ratio of the drag function and ballistic ...
