ABSTRACT:
A munition or round for a firearm comprises a shell casing of synthetic resin material formed internally with a plurality of axially spaced annular ribs which snap into corresponding grooves in the shank of the bullet. The bullet shank is also formed with axially extending grooves to vent the space between the base of the bullet and the bottom of the casing, this space receiving a moist firing charge whose solvent vaporizes through the gaps formed by the axially extending groove.
