Duration: 3:56

This video showcases the rare Sjögren Inertial Shotgun, focusing on its shooting mechanics and unique takedown process. Ian McCollum demonstrates the barrel detachment via interrupted threads and analyzes the long recoil impulse captured in slow-motion. The review highlights the firearm's pre-WWI engineering and its distinctive inertial action.

Quick Summary

The Sjögren Inertial Shotgun uses an inertially locked semi-automatic action. Its takedown involves rotating the magazine tube and barrel, which detaches via interrupted threads. Slow-motion analysis reveals a unique 'long' recoil impulse with a distinct bolt pause.

Frequently Asked Questions

What is unique about the Sjögren Inertial Shotgun's action?

The Sjögren Inertial Shotgun features an inertially locked semi-automatic action. This design uses the inertia from recoil to unlock and cycle the bolt, a less common mechanism compared to gas or pure recoil operation.

How is the Sjögren Inertial Shotgun disassembled?

Disassembly involves rotating the magazine tube to release a plunger, pulling the tube forward, and then rotating the barrel clockwise. The barrel detaches via a system of interrupted threads on the receiver.

What does the slow-motion footage reveal about the Sjögren's operation?

High-speed footage shows the bolt cycling with a distinct 'long' recoil impulse. The bolt travels all the way back, pauses momentarily, and then closes, indicating a specific timing characteristic of its inertial system.

What is the ammunition capacity of the Sjögren Inertial Shotgun?

During the demonstration, the Sjögren Inertial Shotgun was loaded with one shell in the chamber and three shells in the tubular magazine, indicating a total capacity of four rounds.
