Le coefficient balistique est un nombre sans unité exprimant la capacité d'une ogive à conserver sa vitesse. along with muzzle velocity and input for wind speed and direction allows the user to determine what to expect in a flight path for a given projectile/bullet. A high number indicates better flight properties than a lower number. Both are in MS Excel format. This can be useful when comparing cartridges and loads as well as in the field or on the range when you need to accurately project the path of your bullet. expressed or implied as to their accuracy or usefulness. Compare. In ballistics, the ballistic coefficient of a body is a measure of its ability to overcome air resistance in flight. here. have recently "readjusted" some of their BCs to more closely conform to actual below. Computation of the energy and momentum: Program "Exterior Ballistics 2.6" is intended and tested for Windows 2000, XP, Vista, 7 - 10. Vor-Tx® Rifle. Grounds as well as conversions via Shooting Lab, and form Brian Litz's book Important: Since there are thousands of bullet shapes the Ballistic Coefficient calculations made below are not 100% accurate, if you are shooting out past 400-500+ yards your going to need to get the exact BC from the bullet's manufacturer. The G1 and G7 drag models are the aerodynamic profiles of a standard projectile against which your bullet's ballistic coefficient (BC) is being compared, so BC values based on the G1 drag model cannot be used with the G7 drag model and vice versa. is a list of the manufacturer�s published "G1" ballistic provided by the manufacturers as of March, 2009. Firearm Setup. If you below. Under ICAO conditions the speed of sound The ammunition has a good selection of bullets from 85 to 160 grains in various . The boattail design enhances accuracy and an alloyed lead core provides increased weight retention for deeper penetration. BC is what determines trajectory and wind drift, other factors (velocity among them) being equal. It was designed in response to a request for a medium/heavy rifle cartridge combination that was issued from Naval Surface Warfare Center Crane Division in late 2004. Given standard shooting parameters such as bullet weight, BC, velocity, shot angle and weather conditions, the program will present a visual graph of the bullet flight path showing drop, velocity and energy along the way. Eh bien, la réponse directe à la question (car aucune autre information n'a été demandée et en supposant des charges d'usine) est la cartouche de mitrailleuse Hornady A-Max 750gr .50 Browning développée pour les tireurs de cible / match et a un coefficient balistique de 1,05 sur la traînée G1 modèle. See how the 6.5 CM compares to the Classic 308 Win in the 6.5 creedmoor vs 308 ballistics chart! Understanding Bullet BC (Ballistic Coefficient) We hunters love to argue endlessly about calibers, cartridges, bullet weights, and muzzle velocities, but we should be equally concerned with BCs — Ballistic Coefficients.
