Quick Answer
Deburring brass requires using a deburring tool or file to remove sharp edges, then applying a deburring paste or oil to smooth the surface, and finally, inspecting the brass under magnification for any remaining imperfections.
Deburring Tools and Techniques
To properly deburr brass, start by using a deburring tool specifically designed for brass, such as a diamond stone or a deburring file. Hold the tool at a 20-30 degree angle and gently work along the edge of the brass, applying light pressure. For more aggressive deburring, use a 600-grit or higher stone to remove burrs.
Deburring Paste and Oil
Apply a deburring paste or oil to the deburred area and let it sit for 5-10 minutes. This will help remove any remaining micro-burrs and smooth the surface. Use a soft brush or cloth to wipe away excess paste or oil. For an added layer of protection, apply a small amount of lubricating oil, such as gun oil or silicone-based lubricant, to the brass.
Inspection and Finishing Touches
Inspect the deburred brass under magnification, such as 10-20x power, to ensure that all burrs and imperfections have been removed. If any remaining imperfections are found, repeat the deburring process as needed. Once the brass is clean and smooth, it’s ready for loading and use in your hand-loaded hunting ammunition.
