Did a search but did not up with what is thought to be the correct way to break in a new barrel.
A weapon is a highly machined system and a little care should be given when newly purchased. I was told way back in the beginning of firearm care that always break down and do a complete cleaning and inspection of any new firearm. To include running a brush down the bore with oil to try and remove any residual matter from burrs and clogged pores of the metal residing from the manufacturing process; then run a patch. This is more critical these days if you want your weapon to meet up with the ?1? MOA guarantee of a barrel.
There is a process that many refer to as burnishing during break-in. Use FMJ good quality ammo to help polish the inside of your barrel. Not something that does not have the sheen of newly made ammo or something cheap of unknown quality and metallurgy (harder casting the better).
Take one round and fire. Take cleaning rod and use a good copper solvent and clean the bore. Do this every time for the first 10 rounds and you will see the copper fouling is disappearing somewhere around the 8th to 10th round. After the first 10 then every 2 or 3 rounds repeat cleaning until a minimum of 30 rounds are fired (50) being optimum. Rifled shotgun barrels, pistols, all benefit from this break in procedure even black power firearms providing the hardest ball ammo is used.
Things might have changed over the years and I do not shoot competition or try to make 1000 yard shots with my collection. But it is amazing how the barrel will clean up from copper fouling after the first few rounds are fired so there must be something to this procedure.
Is all this necessary....depends... probably not for your everyday plinking kinda folk...for those who want to get the most out of your barrel try it on your next purchase and see what you think. This was told to me by an old WWll and Korean vet who passed away many years ago from Jacksboro, Tx
