Thread: Anyone have a hardys carbon barrel on their rifle? After info on break in procedure

How badly does that copper fouling affect accuracy? Is it a hunting or target rifle Are we talking plus half a moa if so then that's within experimental error and not worth worrying about.
Fouling both copper and carbon will reach an equilibrium point where no more accumulates and theoretically the barrel will shoot consistently at that point.
One of my 223 has fired over 7000 rounds and has only been cleaned with a bore brush and solvent occasionally usually when the chamber gets sticky just a bore snake and light oil is its usual clean. The rifling is streaked with copper way worse than yours there's even a bit in the grooves but it still keeps doing 3/4 moa.
Honestly I'm afraid to clean it thoroughly in case I destroy the accuracy.
