BREAK-IN PROCEDURE

The following procedure is recommended when breaking-in an Oregon Mountain Rifle Co. barrel and or rifle.

  1. Shoot 1 round and clean. Do this for the first 5 rounds.

  2. Shoot 3 rounds and clean. Do this for the next 15 rounds.

  3. Shoot 5 rounds and clean. 

  4. Shoot a fouler round.

  5. 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.

BARREL MAINTENANCE

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.

BARREL INSTALLATION

For Remington, Savage, Bergara, using a OMR barrel nut, OMR recommends 75-90 ft/lbs of torque to properly install barrels. OMR recommends using a 1 1/4" crows foot on torque wrench to achieve proper torque specks. OMR recommends using proper caliber specific Go/NoGo gauges before and after tightening barrel nut to check proper head space.  Gauges can be rented from 4drentals.com

For all "shouldered prefits", OMR recommends 75-90 ft/lbs of torque to properly install barrels. OMR recommends using action specific wrench for your install, along with a quality barrel vise.  OMR recommends using proper caliber specific Go/NoGo gauges after tightening barrel to check proper head space.  Gauges can be rented from 4drentals.com

Once you have installed your new OMR barrel, it is recommended that you have the caliber engraved or stamped before use.  OMR does not do this prior to shipping, because OMR has no idea where your new barrel will time out and properly head space.
