The normal factory load consists of a 200 grain round-nosed bullet with a muzzle velocity of 2080 feet per second. This 200 grain bullet is nearly 18% heavier than the .30-30's 170 grain bullet, and has a 16% larger frontal area. This gives it a substantial increase in power over the .30-30, especially when used on larger game species.
The minimum power factor rule is designed to mitigate the speed and accuracy advantages of smaller calibers. Less-powerful cartridges have less recoil, and therefore can be fired more quickly with the same accuracy. Setting a minimum power factor value requires recoil management skills by all competitors.
Armor-piercing (AP): A hard bullet made from steel or tungsten alloys in a pointed shape typically covered by a thin layer of lead and or a copper or brass jacket. The lead and jacket are intended to prevent barrel wear from the hard-core materials. AP bullets are sometimes less effective on unarmored targets than FMJ bullets are.
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. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
MIL-DTL-46100E specifies a steel of identical hardness. [3] MIL-DTL-32332 specifies ultra-hard steel, with Brinell hardness in excess of 570. [3] A Chinese publication lists 30MnCrNiMo "685" steel as the material used in Chinese rolled armor plates, with a Brinell Hardness of HBW 444-514 (thin) / 429-495 (thick).
The DBP10 cartridge was developed in 2010 and has a hardened steel-cored 4.6 grams (71 gr) bullet, a muzzle velocity of 915 metres per second (3,002 ft/s) from a standard barrel (Type 95 / QBZ-95, 463 mm barrel length) and was designed to match nine different then serving 5.8×42mm chambered weapons. These weapons featured different barrel ...
An optic with too short an eye relief can cut skin at the contact point between the optic and the shooter's eyebrow due to recoil. Expanding bullet: An expanding bullet is a bullet designed to expand on impact, increasing in diameter to limit penetration and/or produce a larger diameter wound. The two typical designs are the hollow-point bullet ...
The SS109 used a 62 gr full metal jacket bullet with a seven grain mild steel tip to move the center of gravity rearward, increasing flight stability and thereby the chances of striking the target tip-first at longer ranges, in part to meet a requirement that the bullet be able to penetrate through one side of a WWII U.S. M1 helmet at 500 yd ...
