Any consensus on best barrel break-in procedure?

[FLshooter]

My uncle sold guns when I was growing up in the 70’s. He told new buyers to shoot 10 rounds and run a patch through it.Throughout my life I used many different break in methods on many different rifles.None made a difference.
I just take out the rifle and shoot it like I normally do. 50 rounds.Maybe one hundred.Then clean it when you get home. That’s what I did with my last two Bartlein barrels and the several other new barrels before that.
