Other bullet manufacturers like Lapua and Nosler also published the G1 and G7 BCs for most of their target bullets. [63] [64] Many of these manufacturer and other independently verified G1 and G7 Ballistic Coefficients for most of the modern bullets gets published and updated regularly in freely published bullet database. [65]
The employed 6 DoF model is however limited to Lapua bullets as a 6 DoF solver needs bullet specific drag coefficient (Cd)/Doppler radar data and geometric dimensions of the projectile(s) of interest. For other bullets the Lapua Ballistics solver is limited to and based on G1 or G7 ballistic coefficients and the Mayevski/Siacci method.
With the improved ballistic coefficient – (G1 BC) of approximately 0.321 to 0.337 (ballistic coefficients are somewhat debatable) – of the new bullet, the 1903 pattern cartridge had an improved maximum effective range and a flatter trajectory, and was therefore less critical of range estimation compared to the M/88 cartridge.

The US Army's Ballistic Research Laboratory measured a ballistic coefficient (G7 BC) of 0.168 and form factor (G7 i) of 0.929 for the 7N6(M) projectile, which indicates good aerodynamic efficiency and external ballistic performance for the bullet diameter. [24] [25] The rounds are loaded to produce a maximal pressure of 290.00 MPa (42,061 psi ...
The bullet has a steel core and has a ballistic coefficient (G1 BC) of approximately 0.304 and (G7 BC) of approximately 0.152. The tip has no distinguishing colour. It can penetrate a 6 mm (0.2 in) thick St3 steel plate at 300 m (328 yd) and 6Zh85T body armour at 30 m (33 yd).
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
The G7 issued a strong joint statement warning that the international community’s response will include “new and significant measures against Iran” if the country moves ahead with sending ...
QuickTARGET Unlimited is an enhanced beta version of QuickTARGET that can take several long range factors into account to make the external ballistic predictions more accurate. For this it can use several drag models; G1, G5, G7, etc. and a custom drag function that uses drag coefficient (C d) data. In January 2009 the Finnish ammunition ...
