Hey folk,
I just bought a Savage 10 GRS in 6.5 Creedmoor and contacted Savage Arms to ask them their recommended barrel break in procedure. Check out what they suggested. Seems an over the top procedure. What are others thought?
Although there may be different schools of thought on barrel break-in, this is what Precision Shooting Magazine recommends:
STEP 1 (repeated 10 times)

  • Fire one round
  • Push wet patches soaked with a powder solvent through the bore
  • Push a brush through the bore (5 times in each direction)
  • Push dry patches through the bore (2 times)
  • Push wet patches soaked with a copper solvent through the bore
  • Push a brush through the bore (5 times in each direction)
  • Push dry patches through the bore (2 times)
  • Push a patch with 2 drops of oil through the bore

STEP 2 (repeated 5 times)

  • Fire a 3 shot group
  • Repeat the cleaning procedure from STEP 1 after each group

STEP 3 (repeat 5 times)

  • Fire a 5 shot group
  • Repeat the cleaning procedure from STEP 1

They recommend the 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.
