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]
Federal Cartridge is now loading a 500-grain (32 g) Barnes X bullet with a sectional density and ballistic coefficient that allows it to maintain approximately 2,000 foot-pounds force (2,700 J) of energy at 500 yards (460 m) and a flatter trajectory than has ever before been attained with this cartridge and bullet weight.
With a 165-grain bullet, the 6.8 Western is capable of matching the muzzle velocity of a .270 Winchester loaded with a 150-grain bullet. The higher ballistic coefficient of the 6.8 Western results in a flatter trajectory at distances beyond 600 yards, which may be controversial for hunting purposes.
These bullets include most Barnes' bullets over 110 gr (7.1 g) and any conventional spitzer bullet of over 115 gr (7.5 g). Hornady's 117 gr (7.6 g) round nose bullet is made for such firearms which have the slower spin rate. Norma loads this bullet in the Weatherby's H257117RN ammunition for owner of such rifles who require a heavier bullet.
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 ...
Due to the necessity of seating heavier longer bullets more deeply into the powder column due to the short design and maximum overall length of the .325 WSM cartridge, velocity drops off as bullet weight increases. This is particularly evident with mono-metal bullets such as Nosler's E-Tip bullets, and the Barnes X bullets.
Monolithic bullets have been used for hunting big game in the USA for decades. The first popular all-copper bullet was the Barnes X bullet in 1986. [7] Since then, most bullet companies have a monolithic bullet on the market, including Nosler E-tips, Hornady GMX, Barnes TTSX, LRX, VOR-TX, Federal Trophy Copper, Winchester Powercore 95/5, Hammer bullets, Cutting Edge Bullets, Lehigh Defense, G9 ...
