ABSTRACT:
The present invention provides a shotshell including a cartridge case having a metal sidewall defining an open end of the case. A charge is contained in the case and retained by an overshot plug which is a friction fit in the case. The sidewall has a thickness of not less than 0.5 mm and may have a formation for engaging a formation on the plug to locate the plug in position.
Shotshell components can be provided as a kit which may include two identical plugs each having a closed air bleed hole which can be extended to pass through the plug. A plug with a completed hole can be used as an overpowder plug while the overshot plug can be used with the hole closed.
