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 700The 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.Jun 27, 2020. #2. I like the shooter app. It uses Brian Litz's ballistics, he's the Berger Bullets ballistic guy. You wont likely get an exact dial solution, it will be a little above or a little below your MOA clicks. It will let you input your range and windage.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)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.

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 ...

Ballistics calculations and formulas for small arms.A bullet is stable if: Sg >. 1 Sd (2-Sd) If you plot that on a graph, you wind up with the following chart: As you can see, there are two regions divided by the line represented by the above equation. If a bullet is inside the stable region, all is good. If it leaves the stable region, it will tumble.

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.

Muzzle velocity is found by using linear interpolation between two velocities measured as a fuction of temperature. Explanation of terms.A ballistic coefficient is a comparative value for a given bullet, showing its relative resistance to drag versus a model projectile that has an empirically established set of drag characteristics. There can be as many model projectiles as there are different bullets, but which ballistic coefficient type is used depends on the model and how ...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 ...The distance above or below the line of sight.

Within 1,000 yards, their predictions were spot on, except again for 0.2- to 0.3-mil deviations at 500 to 700 (sensing a pattern there …). Beyond that, they were off by about 0.1 to 0.2 mil.JBM Ballistics website you can create your own. 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.Ballistic has the option (which I recommend) of using the JBM ballistics engine (which is why, in turn, I recommend Ballistic).
