Please note that the information within this page has now been taken down due to the fact that it lacks the depth and breadth of the information given within my book, the Practical Guide To Bolt Action Rifle Accurizing and Maintenance.
Within the book, I have been able to walk the reader through the step by step process of breaking in a rifle barrel but also, taking individual bores into account such as extremely low fouling bores versus heavy copper foulers. Other factors include custom versus mass produced bores, button versus cut rifling, chrome lined versus standard bores and so it goes on. I have also covered ongoing maintenance schedules.
My apologies to those who were using these online instructions. The plain truth is, there were a number of folk misusing the info. The book in contrast covers the fundamentals before
going into a very detailed step by step process (as do each of the evidence based videos we have been creating - Video learning tab). The original online article was also plagiarised by a U.S gun magazine writer some time ago.
The book that folk say they wish they had 10 years ago.
Heavy copper fouling, in this case with a highly negative effect on accuracy. A correct break in procedure is the key.
Gun drill chatter. This bore needs a good lap to remove the many burrs.
7mm RUM cut away showing racking at the throat after being used for some time.
7mm RUM, revived after applying methods taught in the Accurizing & Maintenance book. These methods help to ensure the shooter obtains the maximum possible round count from any overbore cartridge such as the RUM family.
