Jmb ballistics.

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 ...

JBM Ballistics has partnered with RIANOV to provide integrated ballistics solutions, including the M06 passive ranging calculator, the SOLO calculator and the CSI. The CSI is a new digital angle indicator giving both cant and slope (or cosine of slope). RIANOV™ CSI unit mounted to Remington 700Changing 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 ...The formula for Miller stability is. SG = 30 m/ (t^2 * d^3 * L (1 + L^2)) Where: m is the bullet mass in grains. t is the rifling twist rate in calibers per turn. d is the diameter of the bullet in inches. L is the length of the bullet in calibers. This formula assumes the muzzle velocity is very close to 2800 fps.The first number after the description is the bullet length per JMB Ballistics and the second number is the BC based on Mfg web sites.

Threads. 473,224.The constant 32.2 is the acceleration due to gravity, g, and is used to convert weight to mass: Mass = Weight/g. The free recoil velocity can now be found. V F = (0.000745 slugs * 2700 f/s + 0.000177 slugs * 4700 f/s)/ (0.217 slugs) = 13.1 f/s. And the free recoil energy is given by. E F = 0.5 * 0.217 slugs * (13.1 f/s) 2 = 18.6 ft•lbs.You can do your own experimental calculations using JBM Online Ballistics (free to use). Here is an extreme example, with two printouts (generated with Point Blank software), one showing bullet trajectory at sea level (0′ altitude) and one at 20,000 feet. For demonstration sake, we assigned a low 0.2 BC to the bullet, with a velocity of 3000 fps.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.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 book, among other things, includes software and experimentally measured ballistic coefficients for 175 bullets.

Trajectory (Drift) Calculate a trajectory from bullet, velocity, firearm and atmospheric parameters. Explanation of terms. Library (Select bullet or enter BC and Weight below.) [?]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 ...My understanding is that the JBM range card function uses density altitude.
