heres the problem,, ive got a new model 70-270wsm ive put around three boxes of factory ammo thru it so far,, the last ammo run thru it was win. surpreme elites that had lubalox ,, the barrel has been srubed and cleaned to where theres no copper or fouling i used sweets for the copper,, ive still got what looks like copper in the barrel ?? but like i said theres no more blue on the patch using the sweets,, is this the lubalox coating the barrel and if so how do i get it out ????
