Shooting the MAS-38 Submachine Gun: Second Try

Published on September 20, 2018
Duration: 4:06

This video details a second attempt to fire the MAS-38 submachine gun, encountering persistent cycling and feeding issues. The primary problem appears to be under-length custom-loaded ammunition, preventing reliable chambering and firing. The presenter plans to use higher-quality brass components for future attempts.

Quick Summary

The MAS-38 submachine gun failed to cycle reliably due to custom-loaded 7.65x20mm Longue ammunition being too short. This prevented the bolt from properly chambering rounds, causing malfunctions like light primer strikes and feeding failures. Future attempts will use higher-quality brass components.

Frequently Asked Questions

Why did the MAS-38 submachine gun fail to cycle properly in the video?

The MAS-38 experienced repeated failures to feed and cycle due to custom-loaded 7.65x20mm Longue ammunition that was too short in overall length. This prevented the bolt from reliably picking up and chambering rounds, leading to malfunctions like light primer strikes and jams.

What specific ammunition problems were encountered with the MAS-38?

The primary issue was the overall length of the custom-loaded 7.65x20mm Longue cartridges. They appeared slightly short, which interfered with the MAS-38's bolt action, causing failures to feed and cycle. Some commercial loads were also noted as not being powerful enough.

What are the next steps for getting the MAS-38 operational?

The presenter, Ian McCollum, plans to wait for better quality brass components, specifically mentioning Starline, before attempting to operate the MAS-38 again. This suggests a need for precisely dimensioned ammunition for reliable function.

What kind of malfunctions did the MAS-38 exhibit during testing?

The MAS-38 exhibited several malfunctions, including failure to fire after chambering a round, light primer strikes, and a consistent failure to feed rounds from the magazine into the chamber. These issues prevented consistent operation of the submachine gun.
