A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

The ballistic coefficient of an atmospheric reentry vehicle has a significant effect on its behavior. A very high ballistic coefficient vehicle would lose velocity very slowly and would impact the Earth's surface at higher speeds. In contrast, a low ballistic coefficient vehicle would reach subsonic speeds before reaching the ground. [75]
224 Valkyrie, Uses 6.8 SPC cases, trimmed shorter, and the shoulder re-formed at a lower location due to being designed for using relatively long "high BC" (Ballistic Coefficient) bullets. The neck is sized for .224 caliber bullets. 25-45 Sharps, Uses the standard military 5.56x45 case (also .223 cases), the neck is simply expanded to .257"
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
25×137mm M793 target practice with tracer (TP-T) rounds for the MK-38 being inspected. 25 mm caliber is a range of autocannon ammunition. It includes the NATO standardized Swiss 25×137mm, the Swiss 25×184mm, the Soviet 25x218mmSR, and the Chinese 25×183mmB.
The G7 drag curve model prediction method (recommended by some manufacturers for very-low-drag shaped rifle bullets) when using a G7 ballistic coefficient (BC) of 0.377 yields very similar results in the supersonic flight regime compared to the Doppler radar test derived drag coefficients (C d) prediction method. At 1,500 m (1,640 yd) range the ...
Sectional density has the same (implied) units as the ballistic coefficient. Within terminal ballistics, the sectional density of a projectile is one of the determining factors for projectile penetration. The interaction between projectile (fragments) and target media is however a complex subject. A study regarding hunting bullets shows that ...
The combination of high ballistic coefficients with high muzzle velocities gives the .25-06 a very flat trajectory as well as retaining kinetic energy down-range. The cartridge is capable of propelling a 117 grain (7.6 g) bullet at up to 3,200 feet per second (980 m/s) and energy levels up to 2,500 ft⋅lbf (3,400 J).
