The following procedure is recommended when breaking-in an Oregon Mountain Rifle Co. barrel and or rifle.
Shoot one round and clean. Do this for the first ten rounds.
Shoot three rounds and clean. Do this for the next 15 rounds.
Shoot five rounds and clean.
Shoot a fouler round.
Shoot three rounds for accuracy.
NOTE: Allow barrel to cool to ambient temperature before shooting each series of break-in rounds to avoid unnecessary throat erosion. Do not shoot your rifle in succession until the barrel is too hot to touch with a bare hand.
Once the barrel is broken in, remember to clean the barrel after approximately every 20 to 40 rounds to keep accuracy optimal. A dirty bore is a primary cause of poor accuracy.
