Re: How to Break in a new barrel, gun

Here is how Dan Lilja recommends breaking in his barrels....
Break-in Procedure
For an effective break-in the barrel should be cleaned after every shot for the first 10-12 rounds or until copper fouling stops. Our procedure is to push a cotton patch that is wet with solvent through the barrel. This will remove much of the powder fouling and wet the inside of the barrel with solvent. Next, wet a bronze brush with solvent and stroke the barrel 5-10 times. Follow this by another wet patch and then one dry patch. Now soak the barrel with a strong copper removing solvent until all of the blue mess is removed from the barrel. The copper fouling will be heavy for a few rounds and then taper off quickly in just one or two shots. Once it has stopped or diminished significantly it is time to start shooting 5 shot groups, cleaning after each one. After 25-30 rounds clean at a normal interval of 10-25 rounds. Your barrel is now broken-in.

You may have to be a little more agressive in your cleaning routine than he suggests, since his barrels are lapped, but the routine is the same. Good Luck with the new rifle... [img]images/icons/wink.gif[/img]

Re: How to Break in a new barrel, gun

Some experts belive and I am not saying it is true, as I am trying to make my own conclusion on break in, but some say that barrel makers tell you a long proscess because the more you shoot the more you wear out the barrel and the sooner it needs to be replaced. Your first round fired is the most accurate and so forth. Like I said this is just what some belive.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.

Go to the Hart, Lilja, Kreiger, Shillen, etc web sites. Each one will have a page on barrel break in and what they believe is best. Kreiger will tell you break in and cleaning is up to You. They want you to clean for the first few rounds and then ?????
If you have something that you disassemble and reassemble enough times, sooner or later, you'll have two!
