Recoil. Calculate recoil from muzzle velocity and bullet, powder and rifle weight.The BC, or ballistic coefficient is defined as: BC = w / [i d 2] here the diameter is specified in inches and the weight in pounds and the form factor is found using: i = CD / CD G. The sectional density is defined as: SD = w / d 2. making the ballistic coefficient BC = SD / iJBM. 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).So, for these six loads, we fired five-round groups from a benchrest at 50, 100, 150, and 200 yards. We zeroed our rifle at 50 yards, so that's our starting point. At 100 yards, the subsonic loads dropped more than 7 inches. The Stinger has about 50% more velocity and it only dropped two inches. Moving out to 150, the gulf between the fastest ...World renowned JBM ballistics engine for the most precise, accurate calculations in the industry.

To complement its software, JBM plans to introduce a new hardware product: the BallistiComp. Laster this year, JBM will unveil its new BallistiComp, a portable handheld ballistics computer that measures atmospheric temperature and pressure . 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 Leatherwood ART Scope Trajectory Cam needs to be set to the correct cam setting for your caliber and rifle.

Utilizing the popular and well-designed JBM ballistics code, Table 1. shows a comparison of downrange predictions between G7 and Hornady 4 DOF. A Hornady 6.5 mm 140 ELD-Match projectile is compared for retained velocity, drop, and spin drift. Table 2. shows the samethe ballistics program said it would be about a 12" drop or 4MOA, but it was more like 16-17" drop. this would mean the muzzle vel. was around 2500fps but it was advertised on the site as 2840fps. by the way, the site is awesome, i have been reading for a couple months now and have learned a lot.Ballistic's world renowned JBM ballistics engine delivers the gold standard in calculations that other applications compare themselves to.

World renowned JBM Ballistics engine for the most precise, accurate calculations in the industry; Load library of over 5,000 commercial and military projectiles and factory loads; One-touch atmospheric correction; Ballistic charts to show drop, energy, velocity and compare wind driftThe formulas for the drag function as a function of the drag coefficient can be found here . 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. - World renowned JBM ballistics engine for the most precise, accurate calculations in the industry. - Load Library: 5,000 commercial and military projectiles and factory loads from leading manufacturers or specify your own projectile properties. Includes latest commercial data and military coefficients established at Aberdeen Proving Grounds. 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 ... I have a question concerning data input on the JBM site. In their section for trajectory cards they ask to input the altitude. I'm assuming they are asking for the density altitude, but they don't really say. Anyone know for sure? Are they asking for the density altitude or just regular...The height of the sight (or scope) above or below from the centerline of the barrel. This is required because the bullet starts at a drop of - [Sight Height]. Sight Offset.

Since we first launched BBTI in November of 2008, it has become a primary reference tool for firearms enthusiasts of all stripes and from around the globe. Our initial research data covered the relationship between barrel length and velocity for some 13 common ...A selection of bullets with different shapes, and hence, different ballistic coefficients. In ballistics, the ballistic coefficient (BC, C b) of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in …Ballistics, Reloading and Recreational software for Macintosh and Windows.
