A ballistic coefficient of 0.100 means …World renowned JBM ballistics engine for the most precise, accurate calculations in the industry. Load Library: Nearly 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.Most shooters, especially long range rifle shooters, are familiar with the Ballistic Coefficient (BC). Without getting into the math, I'll define the ballistic coefficient in words as: The ability of the bullet to maintain velocity, in comparison to a ' standard projectile '. A high BC bullet can maintain velocity better than a low BC ...The angle of the tilt of the firearm to the right or left from vertical. Positive angles are to the right. Distance to Chronograph. The distance from the muzzle of the firearm to the chronograph used for muzzle velocity measurements. If the muzzle velocity is estimated, enter 0.0 for this value -- no correction.

Ballistics calculations and formulas for small arms. Drag Function Conversion. Convert a ballistic coefficient from one drag function to another. 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. Ballistics calculations and formulas for small arms.

I've plugged the numbers into jbm ballistics and was surprised that how far that it holds 1000 ft lbs all the way out to 2000 yards with the amax bullet. Most people hold that 1000 ft lbs is needed for white tails and even on elk with good shot placement . . . so even if there is no expansion there will be a .510 caliber "hole" in whatever it ...

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 Library K D and C D. In terms of the newer ballistic nomenclature, C D, we may rewrite K D as. C D = 8/π K D. so that the the equation for G is. G (m) = π/8 C D (m) p 0 | v |. The acceleration of the bullet, due to drag, in terms of C D is. aD = -p π/8 C D (m)/C | v | v. NOTE: that in the preceding equation, the C D is that of the "standard" bullet ...

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.

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 ...

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 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.
