This is not an optional procedure if you expect to get maximum life and accuracy out of your premium barrel.
Clean the bore with JB Bore Cleaner every 2-300 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 in the first half of the barrel. (Breech Half) Push patch through the muzzle and unscrew brush from rod and carefully remove rod from barrel.
4. Remove old patch from brush.
5. Repeat steps 1 - 5 for 5 complete cycles.
Note: A neglected barrel my 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.
