A hollow-base bullet is a firearm bullet with a pit or hollow in its base which expands upon being fired, forcing the base to engage with the barrel grooves and obturating the bore more as the bullet travels through the barrel. Hollowing the base makes the bullet more front-heavy, which improves aerodynamic stability and accuracy.
