Re: Best ballistic calculator ? I mostly use JBM and use Ballistic on the Touch when I'm away from the computer. Ballistic has the option of using the JBM engine, so its results are the same. If you had a small laptop or netbook that you just wanted to haul along to the range, then Litz' program from Berger will certainly work.Ballistic Coefficient The ballistic coefficient for the bullet being used. It is almost always obtained from the manufacturer, but can also be measured. 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.Trajectory μCard - Constant Drop. Calculate a trajectory 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.There is anecdotal evidence that (1) plastic-tip or hollow-base bullets may have larger errors, and (2) the velocity correction above 3600 ft/sec may predict faster twists than needed. Improvement must await new twist-stability factor data. Don Miller 2862 Waverly Way Livermore, CA 94551 [email protected] modified (modified by R. L. McCoy) version of M. A. Morris' RARDLIFT code with corrections for small arms bullets and medium caliber cannon projectiles. Provides interim estimates of lift, overturning moment and yaw drag coefficients. Inputs are very similar to McDrag (above) but it does require the center of gravity location.

The web-based JBM Ballistics Program is one of the most sophisticated and accurate ballistics calculators available — and it’s free. The latest version of the JBM Trajectory Calculator includes field-test-derived actual G7 BCs, as well as bullet drag data from Lapua’s Doppler radar testing. You can also change weather variables, and ...Ballistic Coefficient The ballistic coefficient for the bullet being used. It is almost always obtained from the manufacturer, but can also be measured.

Calculation of the sectional density is straight forward. For a 300 grain, .338 caliber bullet, the sectional density is: SD = [ 300 gr / (7000 gr/lb) ] / [ 0.338 in ] 2 = 0.375 lb/in 2. NOTE: With the common definition of the sectional density, the units have to be converted when used with drag functions, velocity, etc, to convert the in 2 to ...

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. shows a comparison of downrange predictions between …

Pressure: 29.92 in Hg. Relative Humidity: 30%. With the same 6.10 MOA elevation angle. The difference is that for the hunting trajectory, we are going to input this elevation angle and not have the calculation find a new elevation angle for us, so uncheck "Elevation Correction for Zero Range".The Ballistic Edge is further enhanced by the data in the huge Ballistic Library, home to over 5,400 projectiles and factory loads.

Calculate a modified point mass trajectory from bullet, velocity, firearm and atmospheric parameters. Explanation of terms. Caliber (0.100 to 2.000 in) [0.308] [?] in mm.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.

The twist rate (inches per turn) of the barrel. This value is used to calculate stability. It should not be confused with the required twist calculated by Bullet Drag. The diameter of the base of the bullet. For boattails, this is smaller than the caliber. The length of the boattail from the rear of the bearing surface to the base of the bullet.

If the SG of our bullet and gun is 1.4, then the equation becomes: drift = 1.25 x (1.4 +1.2) x 3.237 for a result of 10.52. This means in this example, the bullet will drift 10.52 inches to the left or right depending on which twist the gun barrel has.Its effect is negligible at medium distances, but becomes important around 1000yds and beyond, especially because it can add to other minimal errors and keep you off target. Coriolis effect affects everything not firmly attached to the Earth’s surface. It affects fluids, like air and water, as well as floating and flying objects like ships ...When using JBM Ballistics software, what is the correct drag factor or most accurate drag factor to use with let's say 185 grain Berger BT long range? Log in. Register. Home. Accuracy Ballistics Gear Reviews Long Range Shooting Marksmanship Precision Rifles Rifle Scopes Sniper Rifles. Featured.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 ...Javascript is required.
