About. JBM has been providing free online ballistics calculators and info for approximately fifteen years. During that time JBM has written custom ballistics software for a number …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 LibrarySo, 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 ...With a vast library of nearly 5,000 projectiles and factory loads, rangefinder, range log, and head-up display, Ballistic is a complete mobile companion for hunting or at the range. Ballistic's world renowned JBM ballistics engine delivers the gold standard in calculations that other applications compare themselves to. iPad-Specific Features:

Kinetic energy is a function of the bullet mass and motion. This motion involves the velocity and rotations. It is represented by the following equation. KE = 1/2 M v 2 + 1/2 I w 2. NOTE: this assumes a single rotational axis and forward motion of the bullet. For multiple rotations and non-symmetric bodies, things get a little more complicated.

Ballistic is powered by the JBM Ballistics Engine, one of the most accurate ballistic engines available. Ballistic provides a library of 5,300 projectiles and loads, along with performance data from both manufacturers and military testing. Users can also upload their own ballistic data, making Ballistic the ideal app for handloaders as well.

Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. It will a produce a line graph showing the bullet drop and flight path of the bullet.The 224 Valkyrie is based on the 6.8 SPC rifle cartridge. And because it spits a projectile about the same size as the 5.56 NATO with the much bigger case capacity provided by the 6.8, it does so with ease, effectiveness, and accuracy. In fact, the 224 is known as a longer distance cartridge that remains supersonic way past the 1,000 yard mark ...Jun 23, 2022 · To make one, first generate a come-up table, using one of the free online ballistics programs such as JBM Ballistics. You can also put the info in an Excel spreadsheet or MS Word table and print it out. Above is a sample of a data card. For each distance, the card includes drop in inches, drop in MOA, drop in Mils. Compare these ballistic calculator outputs, particularly the “Maximum PBR” range in the first column. The first is with a 20″ barrel firing M193 at 3300 FPS, the second is a 16″ barrel at 3100 FPS, and the third is a 12.5″ barrel at 2900 FPS. These represent my three favorite barrel lengths for an AR-15.

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 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.

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. That would be a moderate “book load” for a .300 Win Mag deer rifle.Drag Function Array Conversion. Convert multiple ballistic coefficients and find the best new drag function. Explanation of terms.

long range trajectory, wind drift, and impact energy. This project compares ballistic coefficients advertised by four well-known bullet companies (Hornady, Nosler, Sierra, and Barnes) with those measured by an independent source (Bryan Litz). G1 and G7 ballistic coefficients were determined using calculations at the JBM Ballistics web site.

Trajectory (Drift) Calculate a trajectory from bullet, velocity, firearm and atmospheric parameters. Explanation of terms. Library (Select bullet or enter BC and Weight below.) [?]

BC is ballistic coefficient and really describes how well your bullet flies through the air- the closer to 1 the more cleanly the bullet cuts the air. If you look in your reloading manual the particular bullet BC's should be listed. If you don't have a reloading manual to reference you can check out the sierra website:Integrating this equation is much easier when trajectory parameters are required as a function of range. [This vector equation for velocity is derived in the discussion of CD and KD] But, it does introduce another differential equation for time. Simultaneous Equations of First OrderThe Sierra Reloading manual has a section on Exterior Ballistics which provides the differential equations of motion, as does "Exterior Ballistics" and "Mathematics for Exterior Ballistics". Calculation of a trajectory also requires calculation of atmospheric density as a function of temperature, pressure (sometimes humidity, if you want).Ballistic Tip™ Spitzer 2.2 9 V-Max™ 1.9 10 Match Hunting VLD 1.8 11 A-Tip™ Match 1.7 12 Accubond Long Range Spitzer (G7) 1.5 13 Tipped Triple-Shock™ X Boattail 1.4 14 Long Range Hybrid Target 1.4 15 Long Range X Boattail 1.3 16 Accubond™ Spitzer 1.3 17 EOL Elite Hunter 1.1 18 Tipped MatchKing™ 1.0 19 Scenar 1.0 20 CX™ 1.0 #Ballistics calculations and formulas for small arms.
