I am not here to argue cause I really dont know the truth on this, but yes everything I have read is 100 or so rounds through a barrell before its broken in, but you have to get the copper out for it to work. or handlap it right off the bat.
It seems that if a cleaning rod can ruin a barrel that easy, 100 bullets down it would lap it.
What cleaning rods do you reccomend, a brass or coated one, seems brass wouldnt harm a barrell.
