RE: New rifle...breaking-in the barrel?
This is the way I break in all my barrels now I find it works.
STEP 1 (repeated 10 times)
[ul][*][size=2 align="left"]Fire one round[/size][*][size=2 align="left"]Push wet patches soaked with a powder solvent through the bore[/size][*][size=2 align="left"]Push a brush through the bore (5 times in each direction)[/size][*][size=2 align="left"]Push dry patches through the bore (2 times)[/size][*][size=2 align="left"]Push wet patches soaked with a copper solvent through the bore[/size][*][size=2 align="left"]Push a brush through the bore (5 times in each direction)[/size][*][size=2 align="left"]Push dry patches through the bore (2 times)[/size][*][size=2 align="left"]Push a patch with 2 drops of oil through the bore[/size] [/ul]STEP 2 (repeated 5 times)
[ul][*][size=2 align="left"]Fire a 3 shot group[/size][*][size=2 align="left"]Repeat the cleaning procedure from STEP 1 after each group[/size] [/ul]STEP 3 (repeat 5 times)
[ul][*][size=2 align="left"]Fire a 5 shot group[/size][*][size=2 align="left"]Repeat the cleaning procedure from STEP 1[/size] [/ul]They recommend the use of a patch with 2 drops of oil after the cleaning so that you are not shooting with a dry bore. It is also advisable to use a powder solvent and copper solvent from the same manufacturer to be sure they are chemically compatible.

That sounds like a day or two worth of pushin' patches....
The longest part of my break in this weekendwas waiting 15 minutes three times for the UBC to dry.
Shot a 1/2ish inch 5 shot group at 150 yards right outta the gate with a low end load.
Not much into messin' around with things, here........

Barrel break in or premature wear? Kind of toss up sometimes considering that is all you are doing to your gun. I break mine in by shooting them. If they don't shoot well it is usually not the barrels fault anyway and if it is it probably isn't something you are going be able fix easily.
I bet more rifles are ruined by improper cleaning then have been helped by break in procedures. Just my guess though.

This is how it was explained to me.
If you could look through a microscope at the rifling on the inside of a “machined “ rifle barrel (all major manufactures use similar tolerances), you could see the ruff edges on the rifling.
If you were to remove the ruff edges certainly the rifling would be more precise, and the result would be that not only would the accuracy improve but the rifling would not collect as much fouling.
I read a practical field application of this; shot the rifle out of the box, then shot the same rifle with the same ammunition after hand lapping the barrel.
The groups shot after the hand lapping improved by 40%.
Sometimes we need to go back to believing in common sense.
This is simply called craftsmanship; it’s the difference between producing 100,000 of something versus 100.
Probably, most hunters don’t care about the difference between 1/2” MOA vs 1” MOA groups at 100 yards.
Keep in mind that’s a 50% increase in accuracy, yet whatever you are shooting at is still dead.
I’ll leave it to you to decide if it’s important or not.
