If you want to change the way you clean a barrel, start inspecting them with a borescope. Frigging life ruining OCD... put me on a quest to figure out most effective method for me to get a clean barrel and it took 2 damn weeks to figure out fastest method with the stuff I have on hand.
I dont think you need to be a bench rest shooter to realize the benefits of an always clean barrel. In my experience, I miss less. Points have gone up, I no longer question why a miss occurred as I know it's not from a dirty barrel, my sd and es has gone down, I shoot an AR15 from 225-1000yds at paper and steel a lot... like enough to consider getting my blood tested for lead so my experience will probably not match most people. I'm also of the opinion that an ar15, properly built and tuned, can out shoot 99.9% of bolt guns dollar for dollar, and 95% hands down. barrel quality is most of it, keeping it maintained for optimal performance is the rest.
break in... what is break in? i just shoot them and clean them every time, the lapping at the factory should have taken care of any burrs or defects break in process would otherwise take care of.
