NEW BARREL BREAK-IN PROCEDURES
Your new barrel will shoot best if careful attention is given to a proper break-in. Differing opinions exist; however, we recommend that no more than 20 rounds are fired at the time before cleaning the barrel for the first 80-100 rounds.
Procedure for thorough cleaning: in all cases, it is vital that cleaning tools (brushes, patches, etc.) be pushed from the breech to the muzzle and then removed from the end of the rod at the muzzle end.
NOTE: DO NOT drag anything back through the muzzle.
Clean the bore with JB Bore Cleaner after 100 rounds as follows:
1. Work the JB into the patch.
2. Wrap the patch around a worn bronze bore brush (not nylon).
3. Using a bore guide, stroke back and forth for 5 strokes past the gas port. Push patch through the muzzle and unscrew brush from rod and carefully remove rod from barrel.
4. Remove the old patch from the brush.
5. Repeat steps 1 – 5 for 5 complete cycles.
Note: A neglected barrel may require this to be repeated for many more cycles until it is smooth.
Note: The patch will never come out clean as JB is a slightly abrasive compound and is working to polish your throat and bore.
