As I ask around....There seems to be as many different opinions on this subject as there is on which rifle to shoot.
One guy today said he cleans the barrel after every shot for 15 rounds and another told me to just go shoot 10 rounds and clean it then shoot 10 more .....go home and clean it.
I do think that some sort of " Break in " is needed.
Big Country.......I do have some JB paste and may give your suggestion a try.
