Ballistic Coefficient (Velocity) Calculate a ballistic coefficient from near velocity, far velocity and distance between velocity measurement points.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 ...A drag function (or G function) provides the forces on a standard bullet for which the drag function was derived.

Recoil. Calculate recoil from muzzle velocity and bullet, powder and rifle weight. joyce meyer conference 2024huntington iban number Trajectory. Regardless of its bullet weight, the 9mm provides just the kind of flat trajectory that is most conducive to accurate shooting. Bullet drop tends to range from 10 to 12" at 100 yards. That's likely more distance than you'll need for self-defense. 9mm loads frequently deliver a muzzle energy greater than 300 ft lbs.The 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. rennala summoning pool Based on this data, I am confident that best COL length is between 2.53 and 2.60 resulting in sub MOA performance. A bullet seated less than 2.53 is near to the curved o-give. I would perhaps settle on just less than 2.60, say 2.58 for future tests on the Sierra 120 grain. Speed is 2892 fps at the muzzle.
