context_page_description: A hollow-base bullet is an expanding bullet that has a pit or hollowed out shape in its base often intended to cause the bullet to expand upon firing a cartridge in order to expand the base against the barrel grooves and obturate the bore more as the bullet travels through the barrel. It is also used for improved aerodynamic stability and accuracy as hollow-base bullets are usually front-weighted which enhances their aerodynamic stability.
