This guide details an advanced process for removing severe lead fouling from a SIG P322 barrel, a task described as a 'nightmare' due to extreme buildup. It covers the use of specialized solvents, aggressive brushing techniques, and even heat application, followed by polishing and reassembly. The process emphasizes thoroughness to restore the barrel to a mirror finish and ensure proper firearm function.

Quick Summary

Extreme lead fouling in a SIG P322 barrel, caused by Winchester White Box 22 LR ammo, can fill rifling and deform the muzzle. Aggressive cleaning involves lead remover solvents, stiff brushes, and potentially torch heat. Polishing with specialized compounds restores a mirror finish, ensuring accuracy and functionality.

Frequently Asked Questions

What caused the extreme lead fouling in the SIG P322 barrel?

The extreme lead fouling in the SIG P322 barrel was caused by extensive testing of Winchester White Box 22 LR ammunition. This specific ammunition type, when fired repeatedly, led to a significant buildup of lead within the barrel's rifling.

What are the signs of severe lead fouling in a firearm barrel?

Signs of severe lead fouling include lead visibly "flowering" out of the muzzle, the inability for a borescope probe to enter the barrel, and the complete filling of rifling lands and grooves, making the barrel appear non-round at the muzzle.

What specialized tools and solvents are needed for extreme lead removal?

For extreme lead removal, you'll need dedicated lead remover solvents, stiff bore brushes (including heavy-fouling types), a torch for softening lead, and potentially a secondary rod if a brush gets stuck. Polishing compounds and CLP are used for the final finish.

Can a heavily leaded barrel be restored to a like-new condition?

Yes, even a barrel described as a 'nightmare' due to extreme lead fouling can be restored to a mirror finish with persistent cleaning, specialized solvents, aggressive brushing, and potentially heat. This process ensures the barrel is clean, functional, and accurate.
