Abstract
A separate-loading firearm uses a battery-powered electric resistance heating element to ignite a propellant charge. Both ignition reliability and ballistic reproducibility are enhanced when a first portion of the propellant charge is consistently and firmly packed into a cavity formed in a rear surface of a bullet. This first portion may be sealed in the cavity by a membrane. A second portion of the propellant charge is packed within a firing chamber so that it abuts both the heating element and the first portion of the propellant charge.
