All of the WSM cartridges are inspired on the .404 Jeffery non-belted magnum cartridge which is shortened to fit a short rifle action (such as a .308 Winchester). [1] It was developed by Rick Jamison in 1997-1998 as proven in a 2005 lawsuit Jamison vs. Olin Corporation-Winchester division. [2] Jamison was given 7 patents on the cartridge design.
A typical break-action, double-barreled shotgun. A way of closing the breech or chamber is an essential part of any breech-loading weapon or firearm.Perhaps the simplest way of achieving this is a break-action, in which the barrel, forestock and breech pivot on a hinge that joins the front assembly to the rear of the firearm, incorporating the rear of the breech, the butt and usually, the ...
For example, if we compare the .25 WSSM to the .25-06 Remington, we find that the .25-06 requires a .30-06 length action, commonly called a standard or long action.

A rolling-block action is a single-shot firearm action where the sealing of the breech is done with a specially shaped breechblock able to rotate on a pin. [1] The breechblock is shaped like a section of a circle. The breechblock is locked into place by the hammer, therefore preventing the cartridge from moving backward at the moment of firing.
When the breechblock is in the closed (top) position, it seals the chamber from the high pressures created when the cartridge fires and safely transfers the recoil to the action and stock. When the breechblock is in the opened (bottom) position, the rear (breech) end of the chamber is exposed to allow ejection or extraction of the fired case ...
