This is a 7.62x39 ballistics chart (external) generated using our ballistic trajectory calculator. This round is most used in AK-47s and their variants.. The average 7.62x39mm bullet is something like a 123 grain that is fired at an average of at 2,350fps The charting below follows the trajectory all the way to 1000 yards in steps of 50 yard ...Trajectory μCard - Wind Only. Calculate a windage card from bullet, velocity, firearm and atmospheric parameters. Density is calculated using input density altitudes. Muzzle velocity is found by using linear interpolation between two velocities measured as a fuction of temperature. Explanation of terms.To calculate the ballistic coefficient requires two velocities. The initial velocity (V 0 ), and then, at a certain point on the trajectory at the distance x from the muzzle, the V x velocity.To measure V 0 directly is difficult; therefore V 5 and V 100 were measured, from which V 0 was subsequently extrapolated. The ballistic coefficient for one hundred metres is calculated using the ...Power Factor Input Data Bullet Weight Weight of the bullet. Caliber Diameter of the bullet Muzzle Velocity The velocity of the bullet as either (1) measured at some distance from the muzzle (see applicable rule book for measuring methods) You can, but not very accurately. 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.

Bullet Lengths I am in the process of adding bullet lengths to the library so that the drift can be easily calculated. Since I cannot afford a box of every type of bullet to measure them, I am asking for your help to populate the length values.

The Ballistic Wind Kit uses the JBM ballistic engine's wind capabilities to allow shooters to account for nearly any possible wind situation. In fact, the wind kit allows users to quickly program the most complex wind scenarios. Most ballistic applications provide only calculations for a constant wind for the full shooting distance, such as ... Table 6 compares Nosler and Litz BCs for the Ballistic Tip to determine the average overestimate which is 6.33%. The Nosler 120 grain NBT in .284 had the highest overestimate at 12.7%, with the 115 grain .257 NBT and the 125 grain .308 NBT also having substantial overestimates at 10.76% and 9.58%, respectively.

It looks like the 69gr bullets at 2850fps goes sub-sonic betwixt 700 & 800 yards on the JBM website. I have shot the 69's and the 77's both at 600yds and there is a very noticible difference in how they act in the wind though I've shot some good scores at 600yds with the 69's.For the less eager, there are several approximate methods of calculating the required spin for a bullet. The simplest is the old Greenhill formula: T = 150 / L. where T is the twist in bullet calibers, and L is the length of the bullet in calibers. Unfortunately, it's not a very good method, but I include it here to show that longer bullets ...The .300 Winchester Magnum (also known as .300 Win Mag or .300 WM) (7.62×67mmB, 7.62x66BR) is a belted, bottlenecked magnum rifle cartridge that was introduced by the Winchester Repeating Arms Company in 1963.

The angle actually displayed for the up-tilted rifle is a true 5.07 degrees (above horizontal). Using JBM Ballistics, we calculated 5.07° as the angle that would produce a 3000-yard impact with a 185gr .30-caliber bullet launched at 2850 fps MV.

K D and C D. In terms of the newer ballistic nomenclature, C D, we may rewrite K D as. C D = 8/π K D. so that the the equation for G is. G (m) = π/8 C D (m) p 0 | v |. The acceleration of the bullet, due to drag, in terms of C D is. aD = -p π/8 C D (m)/C | v | v.
