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. JBM Ballistic: Standard Edition. Filed in iPhone Apps. Ballistic is the definitive ballistics trajectory calculator for the iPhone.

There is also a group size calculator, also $10.That wasn't what I see when I run the numbers on JBM ballistics. 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.

August 1st, 2013 Updated URLs for JBM Online Ballistics Program. 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.

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 ...

The CSI is a new digital angle indicator giving both cant and slope (or cosine of slope). RIANOV™ CSI unit mounted to Remington 700 ...JBM Ballistics "Trajectory" calculator (not the "simplified" version). You'll need to play with your numbers and find the best "Maximum Point Blank Range." That calculator will allow you to input your vitals diameter (5", 7", whatever).

Ballistics calculations and formulas for small arms. Modified Point Mass Trajectory. Calculate a modified point mass trajectory from bullet, velocity, firearm and atmospheric parameters.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 ...JBM is working on some iOS applications including a ballistics calculator. There are currently no plans to support Android systems. IDPA Classifier A simple iOS application for entering and tracking IDPA classifier progress.JBM Ballistics has some C code on their website free for anyone to download and modify. As long as the person writing the code knows what they are doing and the code is free of bugs, any of the various commonly used methods will work. However, every serious engineer that I know of uses the Point Mass method or an extension of it.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. ... JBM Small Arms Ballistics …CO. 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.

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 range ...

The velocity of the bullet as either (1) measured at some distance from the muzzle or (2) as estimated from reloading data. The on-line ballistics page can correct for the distance to chronograph. (The velocity lost traveling to the chronograph.) Nose Length.

Temperature: 0°F. 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 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.Ballistics calculations and formulas for small arms.

The FTE version of Ballistic includes all of the great features you'll find in the standard edition of the software, plus an advanced head-up display for mounted operation. The HUD provides real-time ...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. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Bullet Length The length of the bullet.Google JBM Ballistics.

JBM is right on the money if you know your velocity, bullet weight, scope height, etc. It is so, "on the money" it almost makes shooting boring. "You sleep safe in your beds because rough men stand ready in the night to visit violence ...This book, among other things, includes software and experimentally measured ballistic coefficients for 175 bullets. The bullets have been added to the JBM Bullet Library using the G7 drag function bullets measured by Bryan are denoted by " (Litz)" in the description. The G7 coefficients should give better calculations than the G1 coefficients ...If you haven't ever used any ballistics programs, you should rectify that problem before purchasing one. The free ones are adequate for most situations that a beginner should be shooting in. The one that I prefer is JBM JBM - Calculations - Trajectory It is very powerful and about as accurate as any other up to 1500 yards. So many things happen ...Calculates the power factor and checks divisions for IDPA, IPSC, TSA, USPSA and SASS. Output shows whether or not the division is made (green/red) and by how much in percent. Calculates the free recoil energy and velocity using firearm weight, charge weight, bullet weight and firearm velocity.The velocity at which the ballistic coefficient entered above is defined. If you only have one BC and no velocity information, use the average of the muzzle velocity and terminal velocity so that you get a new ballistic coefficient representative of the velocity range you are using.There are now hardware solutions with JBM Ballistics solutions so you can have the same accuracy in the field without having to carry a bulky computer. These units solve the equations of motion and do not use approximate methods to find the ballistics solution. For more information, or to ...
