Was I WRONG? SIG P322: Barrel Problem!

Published on July 5, 2022
Duration: 10:31

This video investigates a severe leading problem experienced with a SIG P322 firearm. The presenter systematically tests various .22LR ammunition types, using a borescope to inspect the barrel for lead buildup after each test. The findings indicate a potential issue with the firearm's barrel itself, rather than solely with specific ammunition, leading to the conclusion that the barrel may be out of specification and require manufacturer attention.

Quick Summary

Severe barrel leading in a SIG P322 was investigated using a borescope and various .22LR ammunition types. While Winchester White Box ammo initially caused extreme fouling, subsequent tests with CCI Mini-Mags, Remington Golden Bullets, and CCI Blazer indicated the firearm's barrel may be out of specification, requiring manufacturer attention.

Frequently Asked Questions

What caused severe leading in the SIG P322?

Initial severe leading in the SIG P322 was attributed to Winchester White Box .22LR ammunition. However, further testing with CCI Mini-Mags, Remington Golden Bullets, and CCI Blazer revealed that the barrel itself may be out of specification, as leading occurred with multiple ammunition types.

How can you check for barrel leading in a firearm?

Barrel leading can be checked using a borescope to visually inspect the inside of the barrel for buildup. After firing, a borescope can reveal lead deposits on the lands and grooves, and around the muzzle crown, indicating a leading issue.

What is the difference between plated and bare lead .22LR ammunition regarding leading?

Plated projectiles, such as those with copper or brass plating, are generally considered less likely to cause barrel leading compared to bare lead projectiles. However, even plated rounds can contribute to leading if the firearm's barrel has a manufacturing defect.

What should you do if your SIG P322 experiences severe barrel leading?

If your SIG P322 experiences severe barrel leading with multiple types of ammunition, it suggests a potential manufacturing defect. It is recommended to contact SIG Sauer customer service to report the issue and arrange for the firearm to be serviced or replaced.
