New Rifle break in and cleaning procedure

[Larryjk]

I have used the break in procedure recommended by Shilen Barrel Co. Clean to bare steel after each of the first 5 shots. Then clean after each 5 shots until you have fired at least 50 rounds. I believe in "Blue Goop" on a patch wrapped around a nylon brush.
Shilen says use a brass brush. I have been known to lap the bore with Simichrome before it is ever shot. Sparingly and carefully is the only way to use that product. After break in I believe in 'Moly" treating the bore for the ease of cleaning it provides.
