We do not recommend Re-Chambering 357 barrel liners for a different round, for instance, changing 38 Special to 357. Button-rifled! Made for people who would like to restore accuracy to older guns with rusted, pitted or just worn out barrels. To install, first drill out existing rifling with a drill a little larger than the liner you are installing. For best results, we would recommend grinding or having someone grind a pilot on the drill about the size of the current rifling because this will keep it centered better , then solder the Barrel Liner in place. Or you can also use JB Weld or Acraglas gel because we have had many customers say they worked well. Because we are not gunsmiths, these are just suggestions based on what we have learned over the years and from the nice people that we have come in contact with. A skilled gunsmith with proper tools should be able to install these with no problem. Some might consider using our 357 barrel liners / blanks for your barrel applications such as custom builds.
