I have a NEF inline muzzleloader / 12 gauge rifled shotgun combo. The rifled shotgun barrel is too thin to tap for scope mounts. I bought a steel weaver style scope mount from Brownells and am planning on brazing it to the shotgun barrel. What is the best king of brazing alloy to use? What is the proper procedure to braze it on? I was planning on sanding off the bluing around the area to be brazed. Put a wooded dowel in the barrel to help prevent scaling inside the barrel. Apply paste flux to the areas to be joined. Either use a TIG torch or oxy acetylene torch with a rose bud tip to heat enough to flow the brazing alloy. I want to do this myself because the gun isn’t worth paying a gunsmith to do the job. I am good at brazing and TIG welding however I have never done any brazing on a gun so far.
