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.

Higher muzzle velocity meant a flatter trajectory and less wind drift and bullet drop, making 1,000 m (1,094 yd) shots practicable. Since less powder was needed to propel a bullet, the cartridge could be made smaller and lighter. This allowed troops to carry more ammunition for the same weight.
The rifle must be chambered for either the unmodified .308 Winchester/ 7.62×51mm or .223 Remington/ 5.56×45mm cartridge cases. Bullet weight for .308 Win must be less than 156 grains (10 grams) (typically 155 grain bullets are used), and less than 91 grains (5.8 grams) for .223 Rem (typically 80 or 90 grain bullets are used).
Number 4831 was used to load navy anti-aircraft machine gun ammunition, and number 4895 was used to load United States service rifle ammunition. As these propellants became military surplus after the war, large quantities of different batches were blended together to make products with uniform average performance for sale to civilians.
"Grain foot per second" (gr·ft/s) can be obtained by measuring the mass in grains (gr) (7,000 to the pound) and velocity in feet per second (ft/s), but since their product yields a very large number it is common to multiply by a factor of 1 ⁄ 1000, obtaining the power factor in kilo grain foot per second instead.
A cartridge, [1] [2] also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder) and an ignition device within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of ...
