barrel break in?

I don't do a break-in process, so to speek - just shoot it new and give it a good cleaning after each session initially. After about 200 rounds have been through the rifle I don't really clean it again until the groups start opening up, which is anywhere from 200-500 rounds depending on the rifle.
 
Barrel break-in depends on the final lapping done by the barrel manufacturer. Each one is different....but that clean after each round for 5 shots, then clean after every 5 rounds for 25 shots, so on and so forth is a thing of the past.
 
I clean after each round with solvent for the first five then light oil, this will setup the surfaces of the rifling, then clean after five rounds groups.
my brother's son (1st Lieutenant USAF) did this for a new Rem 700 - 7mm Mag after first five cleaning and scope setup shots, the next five rounds were touching in a line at 100-yards
