i have a savage model 111 .270 with accutrigger and jeweled bolt. while cleaning my bolt today i noticed that the bolt head and front baffle have like black flecks all over them. also on the bolt body there is like black dots a little bigger but not near as many in a straight line down it. none will come off with break free clp or scrubbing. please help me figure out what it is and how to get rid of it
