THE PROCEDURE FOR BREAKING IN A BARREL

There may be different schools of thought on barrel break-in, however, this is what Precision Shooting Magazine recommends: use of a patch with 2 drops of oil after the cleaning so that you are not shooting with a dry bore. It is also advisable to use a powder solvent and copper solvent from the same manufacturer to be sure they are chemically compatible.

Step 1

  1. Fire one round.
  2. Push wet paches soaked with a powder solvent through the bore.
  3. Push a brush through the bore 5 times in each direction.
  4. Push dry patches throug the bore 2 times.
  5. Push wet patches soaked with a copper solvent through the bore
