A soft-point bullet (SP), also known as a soft-nosed bullet, is a jacketed expanding bullet with a soft metal core enclosed by a stronger metal jacket left open at the forward tip. A soft-point bullet is intended to expand upon striking flesh to cause a wound diameter greater than the bullet diameter. Jacketed soft point bullets are usually ...
The official name for .223 Remington in the US Army is cartridge 5.56x45mm ball, M193. If a 5.56×45mm NATO cartridge is loaded into a chamber intended to use .223 Remington, the bullet will be in contact with the rifling and the forcing cone is very tight. This generates a much higher pressure than .223 Remington chambers are designed for. [3]
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)
This causes the bullet to increase in diameter, to combat over-penetration and produce a larger wound, thus dealing more damage to a living target. For this reason, they are used for hunting and by police departments, [1] but are generally prohibited for use in war. [2] Two typical designs are the hollow-point bullet and the soft-point bullet.
This ammunition is optimized for energy transfer in soft targets and offers good precision. [12] The muzzle velocity V 0 and V 100 indicate a G1 ballistic coefficient of 0.171 to 0.187. At the range of 100 m, the 2.7 g ball projectile travels at approximately Mach 1.36 (463 m/s) under International Standard Atmosphere conditions at sea level ...
A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ("jacket") of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. A bullet jacket usually allows higher muzzle velocities than bare lead without depositing significant amounts of metal in ...

Frangible bullets may be lighter or longer than conventional bullets of the same calibre. The jacketed frangible bullet in the centre is longer than the outer soft-point bullets with traditional lead cores. Each of the three .30 calibre (7.62 mm) bullets weighs 150 grains (9.7 g) but the lower density frangible core requires greater volume.
