The following procedure is recommended when breaking-in an Oregon Mountain Rifle Co. barrel and or rifle.
Shoot 1 round and clean. Do this for the first 5 rounds.
Shoot 3 rounds and clean. Do this for the next 15 rounds.
Shoot 5 rounds and clean.
Shoot a fouler round.
Shoot 3 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. DO NOT USE MOLY COATED BULLETS DURING BREAK-IN.
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.
