Larry Potterfield, Founder and President of MidwayUSA, provides an expert guide on polishing rusty and pitted shotgun barrels. The process involves segmenting the barrels, using specialized rubber sanding blocks (concave, angled, and rounded) to back abrasive papers, and progressing through grits from 100-grit aluminum oxide to 320-grit silicon carbide. Cutting oil is recommended for lubrication during the final stages. This detailed technique ensures a thorough restoration of the barrel's finish.

Frequently Asked Questions

What tools are needed to polish shotgun barrels for rust and pitting?

You'll need specialized rubber sanding blocks (concave, angled, and rounded), abrasive sandpaper in various grits (100-grit aluminum oxide, up to 320-grit silicon carbide), and cutting oil for lubrication during the final polishing stages.

How do you polish shotgun barrels effectively near the rib?

To polish effectively near the rib, use angled sanding blocks. These tools allow you to maintain consistent pressure and achieve a smooth finish right up to the edge of the rib, ensuring complete coverage.

What grit sandpaper should be used for final shotgun barrel polishing?

For the final polishing stages, switch to 320-grit silicon carbide paper. This finer grit, combined with a lubricant like cutting oil, will help achieve a smooth, refined finish on the shotgun barrels.

Can I polish shotgun barrels myself at home?

Yes, with the right tools and techniques, you can polish shotgun barrels at home. This guide from MidwayUSA demonstrates a step-by-step process suitable for DIY gunsmithing enthusiasts.
