on a totally unfired after market barrel,i believe a "break in" process is helpful. my question is do people think that there are noticeable benefits to same with a new factory barrel? they are all technically previously fired at the factory usually 1-5r i think. don't know of any factory built rifle that hasn't been test fired a few to make sure they work and are safe.
 
I have a “broken in” factory 700 and one that was just shot. Both shoot sub moa. So in my experience, I see no benefit. So all my other rifles are just cleaned, right out of the box and fired until accuracy gets noticeably wonky.
