First Claim
1. A system for propelling a projectile along a firearm comprising:
- a projectile, having a projectile body, that is propelled along the length of the bore of the barrel and inserted into a cartridge case;
a series of annular chambers, recessed from a main bore wall of the firearm barrel and along the length of the bore of the barrel;
an annular recess in said projectile body;
a series of sealing rings in said cartridge case containing said projectile;
a primer and rear propellant charge, contained within said cartridge case and rearward of said projectile; and
a forward propellant charge, contained within said cartridge case, in contact with said projectile body and forward of said projectile.

Abstract
The construction and arrangement of projectile bearing surface interfaces rearward and forward of a recessed surface chamber of the projectile interface conjointly with the interfaces of bore wall areas segmented by recessed bore chambers which in conjunction effect the deployment/transport/dispersement/development/modulation and transformation of explosive propellant charges sequentially primed and activated rearward and forwardly of the projectile along the bore and in bore wall chambers captively converting high static gas pressure to expansively relieved dynamic propellant gas pressure directly at the projectile reducing firearm barrel recoil while energizing projectile movement along the bore in a closed-system of thermodynamic propellant energy for free flight purposes.
