Abstract
A high strength polymer-based cartridge having a first end; a neck disposed at the first end and a shoulder disposed below the neck to form a bottleneck cartridge. A second end is opposite the first end and an insert is engaged to the second end. A propellant chamber is formed between the shoulder and the insert and has a volume. An extension extends from the neck opposite the shoulder and a cap is formed on the extension, partially sealing the propellant chamber.
