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.

Rifles chambered for this cartridge bullet combination, with a cartridge overall length of 116 mm (4.6 in), have to be equipped with custom made 1,016 mm (40.0 in) long 279 mm (1:11 in) twist rate barrels to stabilize the .416 Barrett MSG projectiles and attain a projected 1,032 m/s (3,385 ft/s) muzzle velocity.
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]
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 ...
What the 6.5-08 provided over the .243 Winchester, .308 Winchester, and to a lesser degree the 7mm-08 Remington was bullets with excellent ballistic coefficients and sectional densities. Since the 6.5-08 was a wildcat cartridge, variations existed between cartridge chambers depending on the reamer used to cut the chamber.
Speer Bullets offers a 130 gr (8.42 gr), copper-jacketed soft-point flat-nosed bullet for use in lever-action rifles. It has a sectional density of 0.23 and a ballistic coefficient of 0.257 [ 7 ] Hornady Manufacturing Company now offers a 120 grain FTX bullet in 7mm/.284" caliber.
Furthermore, the Barnes cartridge is capable of launching heavier bullets than the 7.62×39 and has the advantage of using spitzer bullets and is chambered in strong bolt-action rifles, whereas the .30-30 is commonly loaded with round-nose or flat-nose bullets due to the fact that it is chambered in lever-action rifles with tubular magazines.
However, given the same weight of bullet in both calibers, the .30 caliber has a greater sectional density, and correspondingly greater penetration. [ citation needed ] According to Winchester's original claims, the .32 WS has 5-10% more energy than the .30-30 at close ranges, and less at longer ranges due to increased drag due to the .321's ...
