The .303 British Cartridge, with information on the original Dum-Dum bullet, and the subsequent MK III through MKV hollow-point bullets. Dum-Dum Bullet Testing Archived 2010-03-18 at the Wayback Machine, with tests of dum-dum rounds fired into jugs of water. Bullet Impact Comparison, results of bullets designed for different expansion and ...
A hollow-point bullet is a type of expanding bullet which expands on impact with a soft target, transferring more or all of the projectile's energy into the target over a shorter distance. Hollow-point bullets are used for controlled penetration, where overpenetration could cause collateral damage (such as aboard an aircraft).
The design of the Mk IV hollow-point bullet shifted bullet weight rearwards, improving stability and accuracy over the regular round-nose bullet. [12] These soft-nosed and hollow-point bullets, while effective against human targets, had a tendency to shed the outer metal jacket upon firing; the latter occasionally stuck in the bore, causing a ...
Dum-dum: 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 and the soft-point bullet. Dummy: A round of ammunition that is completely inert, i.e., contains no primer, propellant, or explosive charge.
The Hydra-Shok bullet features a hollow-point construction which contains a distinctive central post in the base of the hollow. This design makes such bullets easily identifiable in autopsy examinations of gunshot victims. [2] The manufacturer stated that the scored jacket and center post design provide a "programmed" expansion. There has been ...
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.

Jacketed hollow point (JHP): Soon after the invention of the JSP, Woolwich Arsenal in Great Britain experimented with this design even further by forming a hole or cavity in the nose of the bullet while keeping most of the exterior profile intact. These bullets could theoretically deform even faster and expand to a larger diameter than the JSP.
