Improvements in a ballistic with a multi-part chamber locking assembly is disclosed to allow the casing ejection and reloading sequence to be temporarily slowed down to capture the optimum amount of ignited gun powders expanding gas, prior to the round exiting the barrel. Large slide component(s) of a firearm are replaced with a multi-part chamber locking assembly. This negates the requirement for a round to move laterally after moving vertically. The round only moves vertically thus mitigating the requirement for any forward motion. The multi-part chamber reduces the weight and materials needed to actuate all components of the ejecting and reloading process, so more energy is available to transfer movement of casing ejecting. The round is fired with a hammer or striker through impingement or a firing pin actuated action on a primer to ignite the propellant.
